What is more revolting: Dudes that eat nose booger or eye booger?

There is particulary foul dude at work that always eats boogers (nose & eye) in the break room (not to mention he regulary scratches is , with hand down pants, and sniffs it). It's gotten to the point that I eat my lunch out in my truck or outside. No use complaining about the dude as he's union dude and they won't do nothing about that sick basturd.
