Okay, well, I am a server, and I do have a few regulars whom I've come to know so well that, yes, they get a pat on the shoulder or an embrace. Non-regulars, or regulars with whom I don't have a "connection," no way am I going into their personal space that personally! And if we could put the tray in the other hand for a moment, what makes patrons think they can grab my arm or snap their fingers at me? Hmm? Or, for that matter, grab or slap other parts of my anatomy that only my physician is allowed to deal with? Huh? Yeah, that's what I thought!
