My personal policy is that if you're too fat to wipe your own ass, you're not handling my food.  A good few years ago I bought a Sunday morning hangover fried breakfast in a UK supermarket.  I shit you not the obese cashier dipped her sausage finger in my fried egg yolk and put it in its mouth.  Needless to say I was fucking amazed and disgusted and it killed my appetite faster than a fat would kill a boner and just walked out. edit: didn't buy...
