Coworker chews with mouth open.
My coworker is a 50 year old man and he chews with his mouth open. It turns my stomach! There is a big congratulations dinner being held for all of us who worked on a project. I do not want to sit at the same table with Coworker. I think he will try to sit with me, because we are in the same group.
If he sits by me, I am prepared to get up and move to another table. Can anyone give me a polite way to excuse myself?
