Having said that, most of the people who work in the service industry in Vegas (and anywhere else for that matter), depend upon your tips to help them get above what is often not a lot more than minimum wage. So if you can blow $20 on a slot machine without a care in the world, why not match that $20 in tips to someone you encounter who made your stay in Vegas more pleasant.

Here are a few guidelines for who to tip and how much, but remember, these are just guidelines. If you win big at the tables, nobody is going to complain if you are more generous with your gratuitites.

Tipping Guide
Taxi Driver	15-20% of the fare
Valet Parking	$2-3 for check in $2-5 for check out
Bellman	$1-2 per bag (more for heavy luggage)
Housekeeping	$3-5 per night (more for messy rooms)
Waiter/Waitress	15-20% (even if comped)
Buffet Waiter/Waitress	$1-2 per diner
Cocktail Server	$1 per drink, including non-alcoholic (even if its free)
Bartender	$1 per drink (ditto)
Showroom Maitre d'	These are rare these days, but $10-20 for better seats
