I see some outrageous tips on here for the service guys are getting at some of these venues. I mean I find myself doing the same thing at times because I get carried away in the moment. There's always some room for negotiation, let's face it, it's a "sale" like anything else. No girl is going to turn you down for $20-$40 less. I just tell them what I want and tell them what I'm willing to pay for it. I've never had anyone turn me down.
