Amen, Brother Jackie. I fear you have more faith in your fellow man that do I if you really think you're going to reach a moron severely retarded enough to "Hidy, Ho" in public. That there's some serious lack of cerebral capacity.
I would never speak to the provider if I saw them - if they saw me clearly alone and said hi, that would be OK as I could either say hi and keep walking like nothing happened or I could decide if I wanted to talk if the situation was right. I have taken providers out to lunch. They just have to look pass off as a potential coworker. Point is, as long as I get to decide no problem.
AND it doesn't matter if the Provider (or Dancer) is alone (HELL, her SO might be in the Men's Room)
It also doesn't matter if you see her in a swing club - again, her "date" may or may not know what she does....and then she has to explain her "date" she knows some old, fat, bald, ugly MF.
