Bloke opposite me eats with his mouth open, the noise (and smell) isn’t good
Used to work with someone that did this on a dinner time. Had a weird technique of eating and talking at the same time that enabled the smell to shoot out in your face if he was stood talking to you. He did it once with a mouth full of raw mackerel. Tried to avoid talking to him after that.
And he had sticky farts as well. He could drop one and the guff would still be there a couple of hours later.
