I might if I was rich and desperate...maybe. Actually, I don't think I would.
I guess you'd also have to be rich and starving to dine in a fine restaurant?
I'm not sure I follow you. I would prefer to have sex with a non-prostitute by a very large margin. In many ways, I prefer to have sex with myself than I would a prostitute. I would have to be rich because I would only ever possibly want to pay for the Spitzer level of prostitute and you have to be rich to do that.
Eating good food, on the other hand, is something that I desire to do. I prefer good food to bad food, and "fine dining" usually means good food. It's also cheaper than the most expensive prostitutes. So, no, I wouldn't have to be as rich or desperate in order to go to a nice restaurant.
