Like with any sales job, you have to learn when it is time to “close the sale”. The clients will take as much free stuff as they can get. In fact, they really don’t want to pay for anything, to begin with. You have to learn your own catch phrases, and how far you can go, before you make it clear that if they want more, they will have to pay for it. Sure, you want to be nice about it. Just stay sexy and “turned on”, but let them know that you really want a little private time with them.
