I'm sorry Padre, I can't go along with all your rules.I once worked for tips, and usually when somebody worked for tips before, they also become good tippers. When you work for tips, you think people who don't tip are the lowest forms of human life, especially if they have money, and still stiff you!
Tipping is one of the best ways to get somebody on you side, especially a mesero, who'll take care of you, get you a good seat, and give you a good run down on the new chicas.
However, if a towel boy knocks early, I would not tip him. But if they hit me up for a dollar, I'll usually give it to them. Besides I'm not sure the chicas take care of those guys, except to tell you to give the guy a dollar. Now according to Sampson, the chicas tip the towel boy, about $4 dollars to knock early in some hotels, in which case if true, they are making out, and don't deserve a tip from you.
Now sometimes the waiters will try to trick you with Mexican change, bringing you Mexican coins, and you thinking it's like a quarter, just give him the change, when he actually the change could be worth a few dollars. I'm sure I have been taken advaneforum.xxxe this way, and one of the reasons why I like just using my favorite waiters, in Hong Kong, I have three waiters I use only.
I never pay up front unless it's an SG, as most of them always insist on the money, and besides it's only $20 dollars. But lately, when BGs ask for money first, I walk, and tell the front desk it didn't work out, and they always let me take somebody else up for free.
