A young man and his date were parked on a back road some distance from town.
They were about to have sex when the girl stopped.
“I really should have mentioned this earlier, but I’m actually a hooker and I charge $100 for sex. “
The man reluctantly paid her, and they did their thing.
After a cigarette, the man just sat in the driver’s seat looking out the window.
“Why aren’t we going anywhere?” asked the girl.
“Well, I didn’t mention this before, but I’m actually a taxi driver, and the fare back to town is $200…”
