Needing to explain it

If you made this tap for use in a public bathroom, you failed. You chose to be different in a way that prevents instantaneous access to water for novice users. It’s not enough to be different – as Marty Neumeier says, you need to different and good.

If you put up the sign, you failed. You heard the complaints from the public but decided that they were wrong and the tap wasn’t broken. Instead of spending your time providing a tap that they could use instantly, you decided to spend five seconds of their time learning to use a tap that’s not fit for the purpose.
