Unlike any other city, state or town, Las Vegas, is not just 24 hours, but it requires more tipping than you can ever imagine. If you are visiting Sin City, it's important that you know one thing, that it's a complete "sin" if you don't take care of the service staff helping you.
Casino dealers call the customers "STIFF" if they don't tip; "GEORGE" if they are good tippers.
Most countries already have the gratuity included within their total, it doesn't work that way in Las Vegas, so before you get the figures wrong, embarrass yourself and upset the help, keep the following things in mind:
Everyone including, but not limited to, bartenders, cashiers, cocktail servers, and VIP hosts, should be tipped. Always make sure that you have the money in your pocket and don't forget to award them with a token of your appreciation for making sure you had great service in this amazing town.
It can get kind of sticky, if you're not aware of how things work. For example, although many places include free Valet services, the attendant is expecting you to tip him no less than $5.00 for protecting your car. If you are really gratuity savvy, you would be amazed at how a little extra gratuity will get the car just a little bit closer; therefore, you will be leaving just a little bit quicker! If you want to be treated like VIP, you need to act like VIP.

Of course it is customary that you tip your waiter or waitress a percentage of the total amount due and in most cases if you are part of a larger group, the tax will be included up to 18% of the bill. Otherwise, it's pretty reasonable to donate 15 - 20% of the bill, and always make sure to round up.
Having a VIP host is very popular for the adult night life in Las Vegas. These particular hosts will make sure that you are taken care of from beginning to end whether it's hard to get tickets, arranging limousines or even making sure that you are personally introduced to your cocktail waitress. These specially trained hosts work very hard in making sure that you are treated and catered too so that you can have the best possible time while in town. What you tip them is entirely up to you, the better the gratuity, the better the treatment. You should expect at least to give them between $75 to $100 dollars. Some have tipped in the thousands. Don't make your VIP host wait, as they make sure you don't have too. Tip them right off the bat.
Bartenders love good tippers! Make sure you budget at least $2.00 per drink or even 15% of your running tab. This may appear to be kind of steep, but remember that bartenders take care of good tippers and you will get not only prompt service but an occasional shot or drink, on the house.
The beautiful and scantily dressed cocktail waitresses take pride in not only their appearance but in making your experience fun as well. They make sure you have your refills, without having to wait. Make sure she receives $1 to $5 per drink and she will make sure that your party doesn't have to stop unnecessarily. Why not? If you are playing, the drinks are free, so what are you really losing?

How About House Keeping Gratuity?
Housekeeping is one of the lowest paid job in Las Vegas hotels and lowest gratuity earners too, a few bucks will put up a big smile on these hard working employees, they will make sure your bed is clean to deserve the gratuity.
Regardless what kind of service you receive, keep in mind that Las Vegas is a "service" town and if you want to have a great time, take care of those that are making it easier for you to enjoy.
