No, you don't!

Maurice:

[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] Baker in Kramer's Pastries:
May I help you, sir? Arthur:
Yes, would you excuse me a moment? I'm sorry, [to Maurice] 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. Maurice:
Well... 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? Arthur:
Yes. 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!
