Dismiss their case and give them a 12 pack of Dial.
Even if one doesn’t shower for a week taking a wet warm soapy washcloth to the armpits and genital areas would do wonders. As for stinky clothes take a hot iron with steam to them to take out the stink. Better yet regular bathing and washing of clothes are highly recommended.
I manage a self storage facility just outside of Tacoma. I keep the door locked, mainly because it’s not a safe area. It also helps with a guy who obviously does not bathe frequently, and does not wash his clothes (he’s always wearing the same clothes). He is not a paying customer, he only comes in to raid my candy jar and talk about things I have no interest in, for like an hour. And when he leaves my office stinks for hours. Anymore, when I see him coming, I just go into the back office until he leaves (I can watch through a security camera on my phone). I’ve had regular, paying customers comment on the smell AFTER he’s been gone for a while. No more. I don’t put up with that. You live in a house with running water. USE IT.
