"Can you please close your mouth when you chew, its a little loud and disturbing." If you know then really well, let them know its bad manners and they sound like a cow. Good luck. Say it like it is! If you're too polite they won't get it! There is nothing more annoying and it's not businesslike either. I had a friend that use to chew gum all the time and snap it to boot! It drove me insane. Finally I just said, "I don't mind you Chewing Gum, but knock off cracking it." She thought I was being over sensitive until someone else told her the same thing.
You can politely let someone know that they chew too loudly by saying something like, "I appreciate your company, but I find the sound of chewing a bit distracting. Would you mind chewing a bit more quietly?"
