It's a serious question. I hate walking into a bathroom and seeing an attendant. Do I really want someone hovering over me when I am doing my business or washing my hands? In a world where I am happy to pump my own gas, do I need someone squirting soap on my hands and handing me a towel? All of which is transparently a bid to guilt me into tipping them for a service I never wanted -- in fact, a service that is a big negative for me. I find myself actively avoiding restaurants I know to have attendants in the bathrooms.
Perhaps being an introvert I have stronger feelings on this, but if other people share these same feelings, even if less strongly, why the hell are there bathroom attendants in the first place? Are they make-work jobs for some out-of-luck relative of the restaurant owner? Or maybe for the local mafia protection racket?
