Giles Colborne’s post Why I Hate Instructions reminded me of a classic example of bad design I recently found at a restaraunt in Devon.
In this instance the instructions were necessary. This was because the mechanism for locking a bathroom door was totally unintuitive and unlike anything I’d seen before.
This should be a warning signal to a designer. If your door handle needs a note explaining how to use it, you know there’s got to be something wrong with the design.
