I worked at a place where a lot of food was brought in and shared, especially baked goods. One person was even paid to bring in (extremely mediocre and occasionally inedible) desserts, (but that is a thread for another time).
A lot of times I'd get the ball rolling by cutting a slice of whatever was offered, then putting the serving utensil on a separate plate to the side. Without fail the serving utensil would end up in the dish. About 15 people would have touched it by that time. As far as I can tell, no one was a big hand washer either, so in my opinion that was a dirty utensil I didn't want touching the food. Am I being germ-phobic or do other people find this gross?
