How much does one tip dealers, bellmen/women, cocktail people etc. etc.?

How do the large hotels maintain an adequate supply of hot water for their guests and the needs of the facility?

In the QoD on 08/22/07, you said the Russian Mafia has been involved in extorting money from online gambling sites. How is this possible? To extort money from someone you have to have something over them don't you?

I recently talked to a friend who said that he heard that somewhere on the Strip is a place where you can get discounts to all the major shows on the day of the shows. Where is it?
