I'm forgetful.

If I forget to log out, my account is open to everyone. If I forget to click "remember me", I have to sign in twice. Making systems that fail safely in case of human error is a good thing.

Although one of my favorite ideas was a system I saw at a hardware store. You could use their terminals to look up products. The terminals had a pressure pad in front of them, and as soon as you stepped off the pad, it ended the session, cleared the cookies, and logged you out.

Out of curiosity, what store (assuming its a chain, or large enough to be known outside local circles)? That's pretty nifty.

Lee Valley. They're a Canadian chain that mostly sell high quality hand tools, cabinet hardware, and gardening equipment, and apparently they're pretty popular for woodworkers in the USA as well.

I miss living within driving distance of one :/
