I was sitting in a cafe this morning watching people come and go and had to laugh at the door.

It was one of those doorways with two doors that both connected at the middle, one was locked, the other wasn’t and there was no sign indicating this state of affairs.

So everyone pushed the locked door first, then when they realised it wasn’t open, went for the unlocked one.

Every single person had a red face when they entered the cafe, and looked embarrassed that they were so DUMB they didn’t know which door was locked.

For anyone that thinks usability is stupid, let this be a lesson to you. When you make something unintuitive, people don’t blame you, they blame themselves. They actually feel stupid. And since that is not a great feeling, the chances of them trying again are slim to none.
