Learning how to properly break the ice and get invited to sit with a customer takes time. Most girls tend to just walk around to every guy in the room and ask "Wanna dance?" and then when he says no walk off. This is the exact wrong approach. Every guy in that room has enough money for at least one dance- you just have to find the right words to get them to buy one. "Wanna dance?" can work in a very crowded room or if a guy is already interested but it will do absolutely nothing to convince a guy who was uninterested to change his mind.
