I remember listening to a Tom Leykis radio caller who said he took one of these dinner whores on a date to an expensive restaurant. Last minute she wanted her fat friend to come who "just broke up with her boyfriend" and wanted to be cheered up. He reluctantly accepted. During the date before ordering he had to use the restroom. On the way back from it just the way the restaurant was situated, he happened to pass right near the table without them noticing, and he overheard his date encouraging the fat friend to order the expensive dish because he'll pay for it, and that it's okay because she already decided she won't see him again.

He then waited until they ordered and decided to fake a phone call, to which he said he'd be back in a second. He got up and walked out to the parking lot and just drove home in his car leaving them with the bill.
