"In Scotland, panic buying of petrol is rampant, with Scots putting in as much as five pounds at the pump."
BRIAN BLESSED, Have I Got News for You. note For transatlantic reference, £5 is around $8, next to nothing in terms of US petrol buying and next to the square root of bugger all in more expensive Britain.
Along with being brave and violent, Scottish people are also often stereotyped as being thrifty, if not outright stingy, with their money and belongings. Within Scotland itself, people from Aberdeen may be stereotyped as being especially thrifty. Probably Truth in Television, since Scotland has always been a poor area compared to England, not to mention being considerably less fertile than the south. Thriftiness is a necessity under such circumstances. This would be perhaps supported by the fact that among Englishmen people from Yorkshire have a stereotypical reputation for thrifty. On the other hand, Ireland has in large periods of its history been considered even poorer but the Irish are stereotyped as impulsively generous.
Part of the reason for the Scottish reputation for thriftiness is the dominance of the (Calvinist) Presbyterian church and the importance of the Scottish school of economics in the tradition of Adam Smith. This has tended to make large parts of the world look on the Scots as embodiments of the Protestant work ethic who are "all work and no play", combining the stereotype of the Thrifty Scot with that of the Dour Scot.
Scrooge McDuck hails from Scotland, probably because of his love of money.
In The Micro-Ducks From Outer Space, when the micro-ducks (who are all no more than three inches tall) offer Scrooge a bag of gold coins in trade, Scrooge has to examine them under a microscope to see them properly and comments "How about that? Gold coins no bigger than a Scotsman's tip!"
Scrooge's whole family is noted to be thriftier than most Scots, and when Scrooge is revealed to be the thriftiest of the family in history, the ghosts of his ancestors carry him in triumph.
Middenface in Strontium Dog is one of these, and usually asks Johnny for a loan whenever he appears.
Astérix and the Britons has a gag where our heroes need to track down a barrel of magic potion that's been hidden among identical wine barrels. A smiling barkeep turns dour on seeing they're ordering one cup for three, asking if they're Caledonian (the Roman name for Scotland).
I'll Be There, a 2002 movie starring Charlotte Church and Craig Ferguson, had Ferguson's drunken, profligate ex-rock star character crash through his mansion's window on a motorbike. While in the hospital the next day, the doctor asked him if he had suicidal feelings; he replied, "Why would I do that? I'm rich, and I'm Scottish."
Flashman's father-in-law is a wealthy Scotsman who does no approve of Flashman's profligate ways and often threatens to stop supplying him with money.
Laura Ingalls Wilder was of Scottish descent on her mother's side. A couple of times in the books, Pa makes an admiring comment about Ma's Scottish resourcefulness with food when they're living in the middle of nowhere.
In the poem "The Lang Coortin'" by Lewis Carroll, the lady is thriftily Oblivious to Love. When her suitor sends her golden rings, she has them made into a chain for her dog; when he sends her locks of his hair, she uses them to stuff a cushion; when he sends her a letter declaring his love, she returns it unread, because the postage wasn't prepaid.
One of the first claims discussed on Would I Lie to You? was from Scottish multimillionaire Duncan Bannatyne of Dragon's Den fame, saying that he'd banned his employees from buying paper clips, forcing them instead to use only the ones that came in with the mail.
Angus Deayton: Lee, what are you thinking about this? Lee Mack: Well, I have to say, the idea of saving money on paper clips is absolutely ridiculous, although the accent is swinging it a little bit... Okay, we think that's true. It was true.
An episode of Dad's Army involves Frazier maniacally hanging onto his stash of gold coins despite all Captain Mainwaring's attempts to get him to put it into his bank.
When David Tennant appeared on Qi, Lee Mack made a joke about Tennant being a Thrifty Scot. Tennant then started waving his pen around like it was a Sonic Screwdriver. He then made an observation that during World War II, the British army had a tank touring throughout the UK, and encouraged people to chuck their spare change into the tank for the war effort.
Tennant: And where did they get the most money? Glasgow!
Lee Mack: Yeah, 'cause they thought it was a big fruit machine. 'Look, I won a soldier, Mummy!'"
This, combined with Violent Glaswegian, is a major part of Billy Connolly's act. "My uncle once dropped ten pence; he bent over to pick it up, and it hit him in the back of the head."
"You may have heard that nasty rumour floating around that copper wire was invented by two Scotsmen fighting over a penny."
One time, Connolly was on Conan O'Brien explaining that he once bungee jumped naked on his travel show. Why? The place apparently had a policy that if you jumped completely naked, it was free. When Conan asked why he did this just to save a few tens of dollars, Connolly replied "You'd have to be a Scotsman to understand".
In Disney's The Wind in the Willows, Angus McBadger is in charge of Toad's finances and thus is very concerned about money.
In the Disney cartoon Pigs Is Pigs, the conflict in the story is partially because the Scottish McMorehouse doesn't want to pay an extra 4 cents to have the guinea pigs shipped as "pigs" rather than as "pets".
In the wartime cartoon "The Spirit of '43", Donald Duck's thrifty side is represented by a Scottish duck(who coincidentally looks like Scrooge but predates hims by a few years.)
In the Looney Tunes cartoon "My Bunny Lies Over the Sea," the Scotsman whom Bugs Bunny messes with is shown as being thrifty. He has only one bullet that he has kept in the family for years, and he is tricked into lowering Bugs' golf score because Bugs makes it seem like an auction and his immediate reaction is to want a lower number.
The Tex Avery cartoons The TV of Tomorrow and The Car of Tomorrow have a "thrifty Scotchman's model" joke; a flashlight on the former, a pedal-operated car on the latter.
This trope originated in 18th-19th century England, and is a shining example of a stereotype being built upon one population only being exposed to a very specific subset of another population (see also: stripy-shirted French onion salesmen). The Act of Union of 1707 linked the English and Scottish economies in a way they had never been linked before, and more or less eliminated all difficulties in crossing the Anglo-Scottish border by making them, you know, one country. As a result, almost every Scot in Scotland who had a desire to get rich beat a fast path down to southern England, where the wealth was. Needless to say, the English recognized the traits that tend to be typical of such go-getters (including thrift) in these Scots, while failing to see the same traits in themselves...
Also, it didn't help that this trope was pretty much enforced on the Scots of the time. The union was driven by an economic crisis in Scotland, a failed attempt to colonise Panama almost destroying the economy.
Aberdeen's reputation for thriftiness is said to have been caused by the fact that the city went bankrupt in the 19th century, which forced it to slash its budget considerably.
A large proportion of the jokes about Gordon Brown while he was Chancellor of the Exchequer played on this trope (ha, ha, the frugal Scot is in charge of the country's finances! It's so funny!). Brown didn't help his case by playing into another stereotype about Scots: that of the "dour Scotsman" who shows no emotion and is consistently gloomy in his mien if not his outlook. The jokes persisted somewhat during his tenure as Prime Minister, given that he was overseeing the country during the financial crisis and money matters were front and center, but strangely, his Chancellor, the equally-Scottish (if born in London) Alistair Darling, did not receive the same treatment.
The Scotch brand of tape gets its name from an incident where the first attempts didn't have enough adhesive on them, prompting buyers to call the makers "Scotch" (which used in this sense is a pejorative). The story goes that the tape was originally manufactured by 3M for Detroit engineers and auto stylists to separate different colors of paint, e.g. in two-tone paint jobs. The original tape only had adhesive on the two edges, leading to bleeding paint. The Detroit guys sent a message to 3M's chief engineer telling him some variation on "take this Scotch tape to your Scotch bosses and tell them to put adhesive down the middle."
The image of Scottish thriftiness is also popular in Germany, where you sometimes see advertisements proclaiming goods at "Schottenpreise" (Scotsmen's prices). In Germany itself some Protestant regions also have a reputation for thriftiness or stinginess, e. g. Swabia (Württemberg), Westphalia and within Westphalia Lippe (a rural region with a strong Calvinist tradition). There is also the common expression preußische Sparsamkeit (Prussian thrift).
As late as the 1980s the US supermarket chain Safeway had an in-house brand called "Scotch Buy", with a jingle to (very roughly) the tune of "Loch Lomond".
