JERRY: You like Chinese food, 'cos I once went to a great Szechwan restaurant in this neighbourhood. I don't remember the exact address... (he spots a mailman crouched emptying a box) Uh, excuse me, you must know where the Chinese restaurant is around here.

The mailman stands, turns and is revealed as Chinese. He takes offence.

MAILMAN: Why must I know? Because I'm Chinese? You think I know where all the Chinese restaurants are? (adopts hackneyed Chinese accent) Oh, ask honolable Chinaman for rocation of lestaulant.

JERRY: I asked because you were the mailman, you would know the neighbourhood.

MAILMAN: Oh, hello American Joe. Which way to hamburger, hotdog stand? (storms away)

Later in the episode, Jerry tells George of the incident:

JERRY: You know, I don't get it. Not allowed to ask a Chinese person where the Chinese restaurant is! I mean, aren't we all getting a little too sensitive? I mean, someone asks me which way's Israel, I don't fly off the handle.
