Mine refers to a classic scene from Reservoir Dogs where after breakfast, a group of criminals are asked to kick in a buck each for tip. Steve Buschemi's character (Mr Pink) refuses on principal until threatened with great bodily violence. Having worked in the service industry and known many fellow service personnel for years, I try and encourage adequate tipping at all times (20% for dining, 10-15% if just drinks).
<Below quote edited for language>
Nice Guy Eddie: C'mon, throw in a buck!
Mr. Pink: Uh-uh, I don't tip.
Nice Guy Eddie: You don't tip?
Mr. Pink: Nah, I don't believe in it.
Nice Guy Eddie: You don't believe in tipping?
Mr. Blue: You know what these chicks make? They make s***.
Mr. Pink: Don't give me that. She don't make enough money that she can quit.
Nice Guy Eddie: I don't even know a f***ing Jew who'd have the balls to say that. Let me get this straight: you don't ever tip?
Mr. Pink: I don't tip because society says I have to. All right, if someone deserves a tip, if they really put forth an effort, I'll give them something a little something extra. But this tipping automatically, it's for the birds. As far as I'm concerned, they're just doing their job.
Mr. Blue: Hey, our girl was nice.
Mr. Pink: She was okay. She wasn't anything special.
Mr. Blue: What's special? Take you in the back?
Nice Guy Eddie: I'd go over twelve percent for that.
