See this happening in London ?
We've seen loads of these in Việt Nam. This was the fist time the camera was handy. A lady pushes her talking scales around while they blare some ear-splitting slogans in Vietnamese ("Giu Tu Phat" perhaps ?). You stand on the scales, hand over your 2,000 dong and the machine weighs and measures you - your stats are presented to you on a paper slip.
