As far as tipping at the clubs, you DO NOT have to tip to get into the club. I don't know why someone said that. Once you are inside and get a drink, the bartenders will all give you their line of crap, "If you tip me good, I will remember you and you will get served quicker next time you want a drink"..... YEAH RIGHT! So you and the thousand other people in the club ALL tip the bartender good and ALL get guaranteed to be served "right away" It is impossible for you ALL to be served immediately, and you wind up waiting regardless. You just have to deal with it.
