Please don't vomit. If you must yack, be certain to do it in a trash can or toilet bowl. It’d be swell if you could just hold your liquor for the allotted amount of time that you’re at the bar, but don’t ruin everyone’s night because you refuse to respect your limit. Nobody likes cleaning up vomit—especially someone else’s.
In addition, if you’re going to pass out, it’s time to go home. The comfort of your own bed is better than any bar, bathroom stall, or floor.
