In the trade do to speak(well was)cheese has been a staple theft item since the eighties I have seen full shelves cleared and caught guys who could barely run due to the weight of the stuff down their coat. Joints of meat were always the favourite along with coffee, spirits, razors,batteries , health and beauty products and tins of red salmon. The tags were poor on chilled items as the cold atmosphere means they do not attach properly, I used to hide them under the proper label , great fun with new starters though- stick a tag in their pocket before they leave the shop, also good for someone you suspect has pinched but cannot prove it- just stand at the entrance and wave a sticker/ tag concealed in your hand then you can search em, ” sorry Pal machine must be playing up”
