The guy in the cube next to me eats all day and chews with his mouth open in a way such that it is slowly driving me to over-the-top insanity similar to what water torture must be like but using the sense of hearing instead of touch. I mean it sounds like spit and food are flying out of there and the adjacent cube wall means that I hear it as loud as it is actually happening. He is a nice guy so I don't want to be rude but it appears as though this has been a lifelong habit. Should I approach the situation and if so how? I really really don't want to wear earplugs or headphones while I work. 


but do have a chat before you get to point where you start listening out for it.
