Actually, if it’s a long time girlfriend, it has nothing to do with getting laid for the evening. It’s more making sure you get laid again, and often. They just want the effort. For cheap, can’t say I was wrong, but Dinger seems to have a better and more impressive alternative. Hell, I'd date him with that dinner.
And Dinger, if you’re a bachelor, last year I went to a sports bar on night shift for lunch, and there were some very drunk, very vocal gals grouped up talking about their EX’s. Apparently lonely, and ripe pickens. Might need a wingman for that though. One to hit on the Fat chick to make the good looking hags jealous, one to buy drinks for the cockblocker.
