I saw a video taken in a huge, crowded bar. This was one of several in a big venue. Shaped like a U open on all but one side. Every time a woman ordered a drink, the bartender turned around while mixing it, peed in it, then handed to her. This was in an actual on the air TV show. The reason they had the camera on him was he was suspected of stealing.
Apparently, not that uncommon. I knew kids working at McDonald’s while I was in high school. They bragged about peeing in cop’s drinks.
fortunately, the big chains now have robotic drink dispensers with built-in ice makers, so opportunities for deliberate contamination of drinks is minimal in THOSE situations ...
nonetheless, given the over-all nature of the kind of people who work in kitchens and bars, i avoid eating out like my life depends upon it ...
