Free beer??? ...yes please...
On a different note though I have noticed a lot of people saying that they would be worried about someone slipping something into a drink before it being offered to them, I had once been out with a bunch of friends and one of the women we were with was slipped something, didn't hit her till the car ride home though... we thought she was just asleep in the back of the car until she had a small seizure and then vomited in the back of the car (thank GOD it wasn't my car)... so my night ended up with me holding an open airway for about 8 minutes while HFD responded with a BLS ambulance, two ALS squads and a pumper... very quick way to sober up...
