How long do you wait before ASKING a stripper out on a DATE?

A word of caution about "lifers" - For some strippers groveling for MONEY may have become routine even when they are not "at work".

Depends on the stripper type:

a) "normal girl": 3rd visit, but no later
b) "party gir"l: 1 visit. We aren't asking her for a date though. We are asking her for sex. First minute is fine.
c) "spiritual girl": doesn't really matter. after 20 minutes is ok, but up to 3rd visit will work too
d) "lifer/loser stripper": No friggin' idea. Yoda? BoneHead, any comments?
