You know the subway near me i eat at twice a week, recently i've ben noticing their glove use as well. They wear them to do EVERYTHING. Then prepare your food with them! I think they think the gloves are just so their hands don't get dirty. from opening that bread cabinet to wiping down the counter where they prepare everything etc they still wear the same ole gloves. its uncomfortable to tell someone to change their gloves.
I agree its gross and its turning me off Subway now.. as soon as i start thinking about my foods cleanliness more than the food itself, i start thinking of finding another lunch spot
