Bill Dearing, who runs Spar Millbrook in Cornwall, runs a ‘what if?’ past me.

“When the display ban came in, Appleby Westward updated my back office printer to print shelf-edge labels to the right font and size; now to say the font is small is an understatement. I can just about read it if I hold it under my nose. So the point is, what about the Disability Discrimination Act? If an adult smoker who is short-sighted asks you to open the door to see a product and they can’t see the price, is that not an offence?”

I suggested that he might have to read out the list to them. Or bounce it off his TSO. Any ideas?
