Food? No, not at all, provided two conditions are met: 1, It's my food and 2, I'm eating it. So long as those two things are true it doen't matter how messy, sloppy, sticky or greasy the food is, I'll happily keep munching away till I'm done. It's straight to the nearest sink to wash up afterwads though. Beyond that, I don't like having anything on my hands(especially sticky stuff, since it inevetably causes even more crap to stick to it), and am usually washing my hands at least hourly at work.
