"..And will it really stop those voyuers who are happy to pay £2 a month to ogle shoppers?."
Those people are truly sad muppets. I get to ogle shoppers for free. Morrisons is just around the corner and you can walk around for hours with no need to buy anything. Just ogle....ogle....ogle.
(They also have air-con so it's a great place to be in the summer [if we get one]).
