[a candy-striper, with a 'Buffy' nametag, approaches Violet who's hauling a dead corpse on a gurny under a sheet]
Buffy: Excuse me. Could you tell me where the coffee shop is?
Violet Newstead: [nervous tone] The what?
Buffy: The coffee shop.
Violet Newstead: The coffee shop? No, I'm new here, I don't drink coffee.
Buffy: I'm new here too. Where do you work?
Violet Newstead: Uh... downstairs.
Buffy: In the morgue?
Violet Newstead: [nervous tone] Yes, that's right!
Buffy: [looks at the body on the gurny] How did he... ?
Violet Newstead: Coffee... too much coffee. I'm just taking him out for some air. Uh, I mean fresh air for me, he's just coming along for the ride.
[Buffy gasps]
Violet Newstead: *What?*
Buffy: Oh, you're a doctor! I'm sorry, I didn't see your badge.
[Violet looks at the badge and finally realizes that the white lab coat she's stolen is a doctor's]
Violet Newstead: Oh yeah... I'm a doctor. So why the hell am I talking to you? Piss off!
