The entire home-buying process (in the US, at least) seems to be built on shady-looking ways to nickel and dime people. I remember telling friends when going through it that it'd be easy to scam me because I got so used to urgent requests to pay some fee for inspections or legal stuff or whatever that I'd just shell out the money without asking questions.

It's got nothing on medical billing. Seemingly random bills from entities you may never have heard of showing up months later even when you paid a shitload (thousands) up-front.

[EDIT] Oh and they may not put enough info on the bill to figure out WTF it's even for, without calling them. It'll have some uselessly-generic single-line item for what was probably multiple things, but you'll have to spend an hour on hold to find out what you're supposed to be paying for.
