I'm at the library, using the computers, and there's a time limit. I have-*checks*-37 minutes left, and I really have to use the bathroom. like, BAD. BUT, if I sign off, go, then try to sign on again, it won't let me. And I'd like to stay online, since I have no computer at home. I can't wait till my online time runs out.....I'll literally run to the bathroom..... (sorry, I just had to get my grief out someway! even if it's not in the way I really want! haha)
I used to work at a library with that kinda system, in ours you could just ask for more time if you want.
