1. I'm 80% water, and I drink like it. My water glass should never be empty.
2. Meal and drink specials without prices. We all know you're charging for it, so just tell me so no one gets a nasty surprise. (And don't make me ask in front of my wife; she'll think I'm cheap.)
3. Bringing a different vintage bottle than is stated on the wine list, and then not telling me. The '97 was a good deal for $100, but the '99 is NOT.
4. Really shoddy wine-by-the-glass selections. Are you really serving Yellowtail with my $40 steak?
