I believe that it (and equally stupid things) do happen.I know it's just an example but would people want to dry their hair in the bath?
As you know, there is at least one of our risk-averse friends who is not only concerned about people using a hair dryer in the bath, but also of their dropping it into a bath (as a 'reason' why metal baths should be {'unnecessarily'} earthed)!
