Would you be willing to pay more for drinks or pay some sort of cover charge so that the bars could afford higher tea money demands?
But if the guy was right about Hotmale's excuse, I don't buy what Hotmale said. The only reason to pay tea money is so that certain members of the local constabulary will look the other way at various infractions. I know of no laws or ordinances that say go-go boys can't be in skimpy underwear. Actually, I don't know of any forbidding total nudity in the bars. I believe if there are any ordinances about it at all, and I'm not sure that there are, it would be a requirement that genitals are not permitted to be exposed. So, I don't believe that tea money has anything to do with why so many go-go boys are in jeans.
If legal matters really are the reasons why the boys wear jeans, then I wish whichever prudes who come up with it would find something better to do. The go-go bars are all in well established gay areas. The interior of the bars cannot be seen from the street. Who would be harmed if the boys are wearing skimpy underwear?
