Gay bar bartenders, who are not necessarily gay bartenders, are usually the most efficient and fair intoxicologists in the drinking universe. I say “fair” because at straight establishments, hot women and rich-looking men (usually jerks) get first priority, and the bartenders frequently take drink orders out of order. Infuriating! This is not often the case in gay watering holes, where the bartenders tend to be the hottest people in the room and don’t need to impress you by serving you first. You need to impress them with the size of your tips.)
Also, gay bar patrons know how to behave (toward the bartender anyway) and will often line up in an orderly fashion at the drink well rather than shouting and waving like the opening scene of The Love Boat all along the bar.
