Does This Booth Make My Bum Look Big?

I could easily do this job in less than a minute. Question - "Am I fat?" Answer- "Yes" or "No". Obviously I'm joking (no, I'm not!) but what will they come up with next? Dentist in a bus stop? Chiropractor in a car park? I suppose this at least brings a service to the people when they are unlikely to go to a clinic for a test.
