These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Are You Being Served?
Big Lipped Alligator Moment: In the 1978 special. The store is celebrating Mr. Grace's birthday; the staff have rehearsed an extended musical number to perform as entertainment. At the last minute, they have to perform something else, so they break into an impromptu version of "Steppin' Out". Okay. Suddenly, Mr. Grace appears, holding a puppet body under his neck, singing a song about "bread and drippin'" which contains only a couple of intelligible words in it. This weird little ditty doesn't fit with the other music at all, and turns Mr. Grace from guest of honor to entertainment with no explanation. Then, the staff segue into "Happy Birthday to You" as if nothing had happened.
Cargo Ship: Mr. Mash's somewhat disturbing attitude towards the female mannequins.
Germans Love David Hasselhoff: Although the show was popular enough in Britain, it is well known as one of the most unexpectedly successful transatlantic transplants, being very popular in the US thanks to years of reruns on PBS.
And in the State of New South Wales in Australia (The ONLY state!) because until quite recently, the biggest department store retailer in that state was called, you guessed it, Grace Brothers.
Replacement Scrappy: Virtually every replacement for a main character. Mr. Grainger's four replacements, Mr. Spooner replacing Mr. Lucas, and Old Mr. Grace replacing Young Mr. Grace. It could be argued the only exception was Mr. Harman replacing Mr. Mash.
Values Dissonance: In 'The Punch and Judy Affair', all the men protest when Mrs. Slocombe wants to play the policeman, finding the idea completely outrageous. Women were not integrated into the main British Metropolitan Police Service until 1973, which is just before the show started running.
