Today I went to a local restaurant that has decent food but always has pretty awful service. There's always something weird going on with the service too, everything seems confused. One time they totaled the bill wrong and we had to go through it ourselves. But today was a new standard in weirdness, and it made me wonder, is it OK for a wait-staff to touch the diners? Repeatedly? She started out doing some touching like we were bonding. Later the touching was apologetic, "I'm so sorry it's taking so long" (shoulder touch). The only places she touched were my clothed back and shoulder but it made me very very uncomfortable. I don't really like being touched that much, I'm not a hugger, etc. So is it ever OK? Or is this a bridge too far?
