late to this, but heres somethin to consider

1. if they have a changed catchphrase, it could be a problem because it could be something offensive. i got a muffy from the void who's catchphrase was the "N" word with l33t speak thrown in. that could be an issue, as many people could get very offended by it, and generally it's just a rude thing ;c
2. if their house has something different in it, it could be obstructing. i.e the marina i got cant get through the back of her house because she has a dresser, a fish and a bed all right alongside eachother and you cant access the other side. plus she has a bunch of bugs and it just sounds awful.
clothes i dont think are a huge issue unless they're a custom made thing and they're inappropriate.
basically, if people dont accept an offer because their clothes are different, it may seem a bit snobbish. but if its something bigger like a house change then people are less inclined too. it really just depends on the person who's buying

(another reason, also, could be for cycling purposes.)
