In this day and time, with so many people out of work... you have to wonder why more ppl don't become "spontaneous restroom attendants".
You know, dress nice and carry a suitcase of toiletries into a crowded public restroom. Be very polite and have your tip jar there as you help each restroom patron.
Maybe work with a friend so you can hand off the $ every few minutes. this way when the police/staff throw you out, they don't confiscate your $ as well.
Tough times, ppl. I'm surprsised we don't see more of this. beggars are on the streets, and offer no service. At least this guy could help make your restroom experience better.
