On tipping, from Reservoir Dogs (heavily edited to keep it clean).

NICE GUY EDDIE
Okay, everybody cough up green for
the little lady.

Everybody whips out a buck, and throws it on the table.
Everybody, that is, except Mr. White.

NICE GUY EDDIE
C'mon, throw in a buck.


MR. WHITE
Uh-uh. I don't tip.


NICE GUY EDDIE
Whaddaya mean you don't tip?


MR. WHITE
I don't believe in it.

NICE GUY EDDIE
So let's get this straight. You never ever
tip?


MR. WHITE
I don't tip because society says I
gotta. I tip when somebody
deserves a tip. When somebody
really puts forth an effort, they
deserve a little something extra.
But this tipping automatically,
that s**t's for the birds. As far
as I'm concerned, they're just
doin their job.


MR. BLUE
Our girl was nice.


MR. WHITE
Our girl was okay. She didn't do
anything special.

These ladies aren't starvin to
death. They make minimum wage.
When I worked for minimum wage, I
wasn't lucky enough to have a job
that society deemed tipworthy.


NICE GUY EDDIE
Ahh, now we're getting down to it.
It's not just that he's a cheap
*******--


MR. ORANGE
--It is that too--


[again]

MR. WHITE
Hey, I'm very sorry that the
government taxes their tips.
That's ****** up. But that ain't
my fault. it would appear that
waitresses are just one of the
many groups the government [screws] on a regular basis.
You show me a paper says the
government shouldn't do that, I'll
sign it. Put it to a vote, I'll
vote for it. But what I won't do
is play ball. [***]

MR. ORANGE
He's convinced me. Give me my
dollar back.
