I'd have to agree with Littlejonny on this one. The lady would have to be pretty special (the total package of looks, personality, promised services, etc.) for me to go back after she denied me any extras the first time. Certainly after she denied me the second time I would never go back. But then again, that's just me. I have had plenty of great experiences with other MPs/SPs without having to make a "$1000 deposit" first.
