Wade, I think his name is - he has some kind of mental disability, can't remember what, but he walks around town a lot, stops at certain places for coffee and to visit, says hello to everybody he passes, attends pretty much any event he can in town, etc.. pretty sure he's harmless, but there's also a general consensus that he weirds a fair few people out..
Mrs. Cross - she's older, starting to lose her marbles, still has her drivers license which causes safety concerns for a lot of people because watching her drive is scary; her car at least used to have a really loud tick so she could be heard from a fair distance off at least. At the store, at least a couple of us cashiers knew the pin numbers for her and Gloria's debit cards (she would often get groceries for Gloria who has trouble getting out of the house) just because it sped the process up for us to do it
Most people that are well-known throughout town are known in a good way, though, generally for volunteer work and such. Ex: Mrs. Busch - sweet old lady, has been volunteering for ages, walks everywhere unless one of her friends is giving her a ride, etc..
Those with a less than stellar reputation tend to just be known at the businesses they frequent (ex: "Piss Pants" who absolutely reeks; didn't matter how cold it was, we would generally open the doors for at least ten minutes after he left to help air out the store and aerosol sprays like Febreeze make me nauseous most likely as a result of being sprayed excessively to cover up his smell)
