Well, first, was he a black guy or a Russian?

Sorry.

This decision is then generally placed on distance. In Vegas, for instance, when I get a ride to or from hotel/airport via courtesy limo, I will give the guy $10-$20, generallly depending on how nice he is. You said your limo was from the hotel to the casino, which I don't really understand, but if it's a fairly short disatnce, I would say $5 is cool - If it's only like 1/2 a mile, then give him 2 or 3 bucks - I just feel like anything under a 5 is kind of lame, unless it's some kind of shuttle and you are riding with a bunch of other random people - in which case 2 or 3 bucks is fine.
