I thought that was due to laws restricting posting prices for alcohol. I know it Missouri at least for a while it was illegal to advertise bar specials. One radio ad for a bar would say "Johnny, Jack, or Jim for one Washington" b/c that was all they could say.

I think waitstaff should check on you about taste after serving the food, but sometimes I haven't even taken a bite of anything yet. Give me a good 5 minutes, not 2 seconds. If it looks like I haven't cut into the entree yet how will I know?
