We take some elderly relatives out for brunch once a month or so and they are really bitchy to the wait staff. It's a nice place and they bitch in a soft voice but nothing is ever right for them.I've never complained to a waiter or waitress. I know what the public can be like and I know I wouldn't last long. I won't be the recipient of abuse either way.
I've never been a waitress and I wouldn't like to be one.
