And then there are is a new version of the "bad feedback" button in Germany. It has a "please wait" light but it will only activate a few seconds after touching the button. So anyone touching the button softly thinks it didn't work and touches harder (some hit it with huge force). Unfortunately the first touch would be enough, but who would expect that a touch takes a few seconds until it's converted into a visible feedback for the user... I don't get it how something like this can get through an user acceptance test.
