In 7 years (30+ trips), only 2 chicks have turned down a drink. 1, said she drank too much the day before (some Dominican holiday party) and was hung over, another was some super fit Venezuelan who was all about fitness and just drank water. For the most part, they all drink and buying a drink goes a long way on that session. The more they like you (and trust you) the more they're willing to get lit. I've had a few get straight sloppy on me and a couple drink me under the table. Its hilarious and a bit of a turn-on when they drop the work voice and start talking shit.
