* One of the rare times a guest has a Moment of Awesome over Basil; Basil is not happy about having a Cockney chap by the name of Mr. Brown in his hotel, especially since he is now advertising to the higher classes. He believes Mr. Brown to be an idiot, even going so far as to patronisingly add that Barcelona is in Spain, when explaining the communication problems with Manuel. When said communicaton problems begin as per usual, Mr. Brown turns around and explains the request to Manuel in '''fluent Spanish,''' much to Manuel's delight. Of course, Basil won't admit to his snobbery [[spoiler: and it turns out Mr Brown is from the CID,]] but it's nice to see Basil's rudeness get shot down when it's not called for.
* Throughout the series, getting Sybil angry is a very large worry. Considering her reaction when [[spoiler:she finds out about the construction folly in episode 2,]] this is a very, very, ''very'' justified worry. Sybil the dragon faced with an optimist... She can kill a man at ten paces with one blow of her ''tongue''!
** [[TheReasonYouSuckSpeech The ensuing argument.]]
--->'''Sybil''': We have used O'Reilly three times in the last year and each time it has been a fiasco! That wall out there is still not done! You had him in to change a washer in November and we didn't have any running water for two weeks!\\
'''Basil''': Well he's not really a plumber, dear!\\
'''Sybil''': Well then, why did you hire him? ''Because he's cheap!''\\
'''Basil''': Oh, I wouldn't call him ''cheap'', Sybil!\\
'''Sybil''': Well, what WOULD you call him, then?\\
'''Sybil''': And the reason he's cheap is because he's no bloody good! ''(she stomps on Basil's foot)''\\
'''Basil''': OOH, Sybil, you do exaggerate! I mean, he's not brilliant...\\
'''Sybil''': Not brilliant? He belongs in a zoo! ''(she kicks Basil in the shin)''\\
'''Basil''': OW, Sybil, you never give anyone the benefit of the doubt!\\
'''Sybil''': He's shoddy, he doesn't care, he's a liar, he's incompetent, he's lazy and he's nothing but a half-witted, thick Irish joke!\\
'''Basil''': [[RightBehindMe Hello O'Reilly]], we were just talking about you, and then we got on to another Irish builder we knew. God, he was awful!\\
'''Sybil''': I was talking about you, Mr. O'Reilly.
** And then O'Reilly thinks Sybil is joking. [[NoHoldsBarredBeatdown Not the]] [[TheReasonYouSuckSpeech right reaction.]]
---> '''Sybil''': O'Reilly, I have seen more intelligent creatures than you lying on their backs at the bottom of ponds! I've seen better organized creatures than you running round farmyards with their heads cut off! Now collect your things and ''get out''! I never want to see your or any of your men in my hotel again!
* The end of "The Hotel Inspectors", where after dealing with the insufferably picky Mr. Hutchinson for the entire episode, finally just slams two cream pies into his face and crotch, pours a pitcher of milk into his briefcase, and throws his prissy ass out the door.
-->'''Basil:''' And if you ever come back, '''I shall kill you.'''
** Creator/JohnCleese once said that the only thing he didn't like about that scene was that the screams of laughter from the studio audience drowned out that last line.
* Another example of a guest being so much ruder than Basil that we're completely on his side is the bratty boy from "Gourmet Night," and dear lord is he on a roll this time:
-->'''Boy's mother:''' He's very clever, rather highly strung.\\
'''Basil:''' Yes, yes, he should be.
-->'''Boy:''' ''(about his chips)'' They're the wrong shape.\\
'''Basil:''' Oh dear, what shape do you usually have? Mickey Mouse shape? Smartie shape? Amphibious landing craft shape? Poke-in-the-eye shape?
-->'''Boy:''' ''(about the mayonnaise)'' That's puke, that is.\\
'''Basil:''' Well at least it's fresh puke.
** To top it off, he gives him an "accidental" slap on the head too.
* In "Communication Problems", one of the few times the show gets you on Basil's side, because his obnoxiousness is fully justified as he's standing up to an insufferable and dishonest persnickety customer.
-->'''Mrs. Richards''': When I pay for a view, I expect something more interesting than that!\\
'''Basil''': That is Torquay, Madam.\\
'''Mrs. Richards''': Well, it's not good enough.\\
'''Basil''': Oh? And may I ask what you were ''expecting'' to see out of a Torquay hotel bedroom window? Sydney Opera House, perhaps? The hanging gardens of Babylon? Herds of wildebeests sweeping majestically--\\
'''Mrs. Richards''': Don't be silly. What I wanted was a view of the sea.\\
'''Basil''' ''(pointing)'': You ''can'' see the sea. It's over there between the land and the sky.\\
'''Mrs. Richards:''' I would need a telescope to see that!\\
'''Basil''': Then may I recommend you try moving to a hotel closer to the sea! Or preferably in it.\\
'''Mrs. Richards''': Right, now, listen to me: I'm not satisfied. However, I have decided to stay here. But I shall expect a reduction.\\
'''Basil''': Why? Because Krakatoa's not erupting at the moment?
* While it ultimately backfires badly on him, Basil within another rant from Sybil, quickly silences her with a firm BigShutUp in "The Psychiatrist".
-->'''Basil:''' I'm fed up with you, you rancorous, coiffured old sow. Why don't you syringe the donuts out of your ear and get some sense into the dormant organ you keep hidden in that rat's maze of yours?
* The American guest, Mr. Hamilton, destroying Basil's "we have had many satisfied customers" act by asking the other guests (whom he had not interacted with) if they were satisfied. They were not.
* In 'The Kipper and the Corpse', Basil [[spoiler: escapes all consequences by climbing into a laundry basket while his wife is left to mop up his mess. Cue end of episode]]. RefugeInAudacity, obviously.
* In "The Anniversary", [[OnlySaneWoman Polly]] finally gets tired of Basil dragging her through insane scheme after insane scheme, gives him a TheReasonYouSuckSpeech ''and'' forces him to pay her out the nose before agreeing to any further plans.
