While you're out eating with friends, and the person across from you is chewing their food so loudly its all you can concentrate on you realize you don't want to invite that friend out to lunch anymore. If the word gets around that you are a loud, obnoxious chewer nobody is going to invite you out to lunch and you probably won't get many dates. The dates you do end up getting won't go very far and you could possibly be destined to live alone forever.
Chewing with your mouth open can lead people to believe that you live in a trailer park and weren't brought up properly, even if you have a degree in biochemical engineering. Say you're a well known biochemist and you are asked to dinner by a prospective boss. Everything is going well until the food arrives, and the prospective boss is asking you questions and instead of waiting until you've swallowed to answer the questions you answer while scarfing down your dinner. It makes you appear like you have no manners or previous human contact. Nobody wants to work with that kind of person.
For me, I want to punch anybody who sits there and lets their food hang out of their mouth while rattling off the latest gossip. I'm not the only one who feels that way, "Many a times I just want to walk up to someone when smacking food and smack them." It just grosses me out beyond anything else. I learned the embarrassing way to chew politely. My friend pointed it out while we were at a nice dinner with her parents when I was about nine. Since that day, I've always chewed quietly with my mouth closed.
Basically, people that chew their food with their mouths open don't belong in...
