Yes, there are people with bad habits and I don't like that at all, and not only the ones you mention but more, that maybe are not so invasive but they bother me, eating with the mouth open and others that are more disgusting.
I think a lot of it depends on education and respect for others... if there were those two components we wouldn't have to put up with such things.
There are some very dirty people!
Very dirty fuckers out there for sure. Disgusting.
Yes, there are! Many times it even makes me nauseous....
of course, there are all kinds, there are some very correct people but I always find a nasty one.
