I see these guys mostly at strip clubs, but I remember one at I believe Barbary Coast a few years back as well. I tip them a dollar a piss, but it irks me a bit to know that they probably make more money than I do. Think about it. If every third guy gives them a buck in a high volume joint with drinking going on? That's what makes me wonder whether they have to 'tip out' the establishment and/or are responsible for buying all the paper towels/toilet paper, etc. I can see it from the businesses' end that they are basically getting around the whole bathroom privacy thing with a de facto security guard in the bathroom, but you'd think they'd be getting a financial kickback as well.
