What's up with bathroom attendants

I guess this is rant day, since following my time suck post I have a not so serious question about bathroom attendants. What is the deal with you guys? What purpose do you serve? I'm pretty sure I can get the soap out and turn on the faucet for myself. I do it often. And can I please get a towel that you haven't touched? Thanks very much. And now I'm supposed to tip you?

I know you guys have to make a living but come on.
