haha I use to know this girl who never brought her own drinks, drank all her friends drinks and had random strangers buy her drinks too. took 2yrs before someone (she had it coming) slipped her something. she rung me up 3 days after a night out and was most upset about being passed out for 2 days. then she was even more upset when I showed no symapthy for her. its like just a thought - buy your own drinks the world doesn't owe you anything.
