chessmaster and twentyfive highlighted two scourges of the PL world in a different thread about various approaches PLs take to the hobby ( tuscl.net ).
The first was "White Knight Syndrome", where guys infected believe they are Capn' Save-a-Ho and keep trying to rescue strippers from da game. It's a dirty game to those suffering from WKS, but fear not because they will save the day. Or night. Or that really weird time when you can't tell if it's late night or early morning but the guy is still hiding in the bushes after following a girl home.
Then there's "Smartest Guy in the Room Syndrome". It's known to be less troublesome to dancers, but can still pose challenges to the tranquility and civility of your average strip club. As observed by nicespice, at the club they are "the jolly talkative ones, who will never buy dances but will order a drink." Occasionally bouncers and other customers will attempt to cure those afflicted with SGRS (sometimes mispronounced es-jay-gee) by punching them in the face.
Any others conditions we can name?
The Boyfriend, ass that thinks dancer us in a relationship with him not his money.
