What BGs do is play games, and I don't mean Con4 or dice box. The two usual games are:
1. The short game, which means getting the most money they can get on any given night. If the evening is young, they will try to go ST, so they can get another date or two, later on. If they have been going every night with the same guy, they will do ST in the afternoon, if they can, and if a different guy walks in their bar before their regular, and offers double what he is paying, they will go with him, and make excuses to the regular guy(I was sick, too drunk, had to help out sister, etc.). This sort of girl doesn't think beyond today, and is looking to maximize profit every day.
2. The long game, which could as well be called, Go For the Visa game. They will tell you they love you and try to get you to fall for them. If possible, they will get you to sponsor them. But they do this with every guy they meet, and, often have 3 or 4 BFs, and sometimes multiple sponsors, as well. Whoever gets them the visa first is the loser, although he may think he is the winner. They are the winners!!
Am I cynical? Na-a-a-h! It may seem that way, but just ask any guy who has lived in LOS for any amount of time and he will tell you the same.
