@LadyShadow and @MuddyBoots: Of course i realize that if he was not getting tipped he would have been hostile. It was a fancy place and i was there for four hours. You tip at the end, at the final bill. So it wasn't that i was not tipping generously. The whole time he was serving me he was working for his tip. And stupidly i did tip 20% ~ my standard for upscale places. I felt that i wanted to keep good relations with staff for future visits. Now i'm not so sure.

Gee, you two must really think i am stupid to have suggested such an obvious explanation.
