yes, we had the tong discussion before. Fingers picking up every other person's germs from the tongs then inserting those germs into the mouth on the nachos or vegetable sticks. I now use a cocktail napkin to grip the tongs! Or the cocktail napkin to grab the food item. Or rarely, if possible, carefully grab food items that are separate and apart from other food items such that I won't touch the other food items.
Even the food in the UA clubs in individual wrappers, the wrappers are touched by other people, and then you use your hands to open the wrappers and put the food (cracker, cheese, carrot) directly into your mouth. It's a germapalooza. I got so sick the last time I passed through a UA club.
