Or they think it's a more socially acceptable way of paying for sex. They fail to realize that accepting unsolicited gifts obligates no one to anything.

A young man I knew from the University we attended once took me to a very nice restaurant. We had a pleasant time, but there was no real chemistry and I wasn't feeling like this was a relationship I'd want to pursue. I was driving, as he had no car. He invited me back to his dorm room for some "making out." I said, "No thank you." I waited for him to exit the car. He told me I had a "reputation." That got a hostile rise out of me, until he went on: "The guys warned me about you. They told me even if I bought you a nice dinner and a bottle of wine, you still wouldn't put out." Part of me wanted to just crack up laughing. It was absolutely true. Another part of me wanted him never to make that mistake with any woman, ever again. I reached into the bottom of my purse, where I'd been throwing loose coins for probably a month, grabbed a fistful of change - enough to hurt - and threw it at his face as he scrambled out of my car and landed on the pavement.

He did call, later, to apologize.

He did NOT ask for a second date. :)
