A guy and his date are parked on a dark back road some distance from town and the guy wants to have sex with the girl. She says, "I probably should have mentioned this before, but I am a prostitute and if you want to have sex with me, it will cost you $20." The guys reluctantly pays the girl and they get it on. Afterward, the guy just sits in the driver's seat and does not budge. The girl asks, "Why aren't we going anywhere?" The guys replies, "I probably should have mentioned this before, but I am a taxi driver and the fee to get back to town is $25."
