This particular situation made me roll in laughter like a child. Just check the dialogues out. All this effort by the starving duo was to have creampuffs for free.
Maurice (Oliver Platt): [has just finished eating a pastry; part of a scheme to get free pastries] I hate them.
Baker in Kramer's Pastries: Oh, I'm sorry; to each his own. There's another bakery shop down the block whose wares might be more to your liking. Thank you for coming in.
[to Arthur (Stanley Tucci)]
Baker in Kramer's Pastries: May I help you, sir?
Arthur: Yes, would you excuse me a moment? I'm sorry,
Arthur: I couldn't help but overhear, excuse me, sir, um, but may I say that your rudeness to this hard-working gentleman is uncalled for.
Baker in Kramer's Pastries: Please, sir
Maurice: I beg your pardon.
Arthur: No, I beg yours, sir. I happen to know that this gentleman
[refers to the baker]
Arthur: is one of the finest pastry chefs on the Eastern seaboard.
Baker in Kramer's Pastries: Well, thank you.
Arthur: You're welcome.
Baker in Kramer's Pastries: Do I know you?
Arthur: Of course you do.
Maurice: What's your point?
Arthur: My point is, sir, that you would not know a good creampuff if it jumped up and licked you on the ass.
Baker in Kramer's Pastries: Sir, it's just a difference in taste.
Arthur: No, no. this man is clearly an imbecile.
Maurice: Ah, an insult!
[quietly to Arthur]
Maurice: I'm in-I'm insulted?
Maurice: I'm insulted! Well, I am!
Arthur: Oh, well good-good-good-good! Well, I'm glad you are! But I'm sure you're not as insulted as this gentleman!
Baker in Kramer's Pastries: Oh, I'm not insulted.
Arthur: Oh, yes you are! The man works all day like a mule to support his miserable family.
Baker in Kramer's Pastries: Well, here now, my family isn't miserable. We're all quite happy!
Arthur: No, you're not! You're miserable and pathetic, look at you!
[ignoring his protest]
Arthur: All day, working like a lackey from rise to set sweating in the eye of Phoebus!
Baker in Kramer's Pastries: I love my work!
Arthur: No, you don't!
Arthur: What a fool you are!
Baker in Kramer's Pastries: I am *not* a fool!
Arthur: Oh, yes you are!
Maurice: Sir, you really sholdn't talk to this gentleman that way. You like the cream puffs. I *don't* like the cream puffs.
Arthur: FUCK THE CREAM PUFFS! THIS MAN IS A SLAVE AND AN IDIOT!
I'm sure many of us have been in such similar catch-22s in our lives!
