superfat grocery clerk Not really a long story this time, just wondering something. Why do fats so often have that white gunk in the corners of their mouths? The cashier at my grocery store had just TONS of it sitting there crusting up and it absolutely disgusted me. She also could barely speak without wheezing, and had dandruff like crazy. She was probably 5'7" and about 400 pounds. Oh, and she had a fitbit.
