Watch out!

(picture of metal bar) There is a gate at this library consisting of a metal bar. It is to keep you from leaving with books you haven't checked out. I get real nervous when I walk through the gate; I think it's the height of the metal bar. If you tried to walk out with an unchecked book, the gate would lock closed. Can you imagine walking into the locked gate with the bar at this height?

Design suggestion

When you design something, you need to test it with a variety of people to make sure it doesn't have any annoying side effects.

After thought

This library was remodelled recently. It doesn't have these gates anymore.
