As we waited for our food to be warmed up we watched the cashier stand at the register picking up ice cubes from a cup, put them in her mouth, suck or chew a couple times, spit the remainder into her bare hand and then toss aside onto the floor behind her. Swipe a card, give receipt and put more ice in her mouth and repeat the process. Absolutely the most disgusting thing I've ever seen happen in a food establishment. If that's what's happening in front of all customers and coworkers I can only imagine what's happening behind the scenes.
