This is gonna be a strange question, but here goes... I have never used a wash n fold service before, but I am at the point where I think I would like to. I live in an apartment building and the washer/dryers are in another building. It's a pain in the neck walking all the way there with all my clothes only to find all the machines occupied. Especially in the winter. Anyway, a lot of my clothes gets really, really sweaty and stinky because I work out a lot. After they sit in the hamper a couple days, they are still damp and unpleasant. Will this be a problem with these services? I know, I know, they are used to dirty clothes. But these can get pretty bad. Also, should I tip them?
