I was at Cholo's the other day... after drinking 4 or 5 bottles of a cold beverage, I suspected that somebody might have put beer in the bottles... but I was not sure so I kept drinking. After another 3 or 4 my suspicions grew but I could still not quite be sure??? I asked the people around me "is there BEER in here" but I did not get a conclusive answer so much as laughter and slurred replies. Waking up the next morning, I had a bit of a headache. I DEFINITELY now think that is was beer.
