My sister used to work next to a loud eater who she called "Slurpy." I didn't understand why it bothered her so until now.
I share an office with a guy who is a loud eater. Every morning, coffee. Sluuurrrppp. Every sip, long after it could possibly be necessary because the coffee is hot. Lunch: sandwich and chips. Smack, chomp, slurp on the beverage. I never look at his face during this but clearly he is chewing with his mouth open. I think he may have loose dentures. Sometimes the sound of it is almost nauseating. This is five days a week, y'all!
A few days a co-worker came to talk to him while I was eating, and he did the usual with the added bonus of talking with his mouth full. I had to leave the room.
Other than that and the occasional excessively gassy day, he's a good officemate. He is socially awkward and I think he would feel humiliated if confronted with this, so I do not intend to do so.
I'm curious about your experiences with this type of eater, particularly if you deal with it on a regular basis.
