Input: I work at a university in Ontario, Canada and there are hundreds of staff in this school. So I don't know the guy in question, have no relationship with him. Frequently he takes his lunch break in the staff room at the same time as me (which is pretty large, could seat around 20-30 people). 

Very rarely does anyone chat– People usually come here just to eat lunch or take a break. Additionally, there's usually only 5 people in here at any one time so it's very quiet. 

This guy eats with his mouth open, and it's the sound that really bugs me. It's all you can hear. If I told him to stop chewing and eating his food like that, would I be the asshole?
