NJ, I don't think I would classify using the ham that's left on the bone as something unappetising. The ham that's left on the bone is usually really tasty, but because it's so close to the bone, it's impossible to slice in a presentable fashion. Unless it's also out of date, I wouldn't think of it as a bad thing not to waste that.

And about that glove thing: I have seen that so many times that people were wearing gloves, than they pick up a rag to wipe up a spill and make the next sanwich without changing the gloves. Or as LS has mentioned, handle money in between. I always had to shake my head when thos same people tell me that they wear them for hygiene reasons.
