Loud chewing and chewing with your mouth open

                                    

                                          
Let's start this by saying CLOSE YOUR MOUTH.
I don't want to hear your food become one with your saliva, much less witness your meal become a corn refried bean looking mush.
It's disgusting. You have teeth, why does it sound like your gums are smacking together. You sucking a dick or eating a burrito? Seriously, just close those lips and keep them that way. If you're at home sure. I don't pay your bills do what you want. Yolo I guess.
My mom taught me that I shouldn't talk with my mouth full. And if I need to, I cover my mouth to say a quick comment or signal the person to let me finish chewing and swallowing.
If you have some sort of issue with your mouth or something then yeah, you have an excuse (not what it can be, root canal? New braces?Idk) If you're just a dirty slob get your life together and close your mouth and use the napkin you were provided.
Table side manners should just be a thing. It's not oppression or whatever someone would claim, it's just being a decent human being with general knowledge of table manners.
(But if you're like in a country where slurping noodles is the polite thing to do you better slurp those damn noodles)
