Most times I go to a supermarket, I see stuff which customers changed their minds and dump things in the wrong temperature section. Over the past week, I have seen:
. Cheesecake in the bread
. Ice cream in the cheese
. Chilled ready meals in the frozen
99.9% of this will have to be disposed off as too warm, too frozen etc
Customers should put stuff back themselves if they have changed their minds. They picked it up, they changed their minds, they should put it back.
A friend works at a supermarket. She worked out about £120 of stock is disposed per day as customers left the food in a different temperature section. Sometimes if could be for example, a pizza, found a better offer in the chilled section then leave the frozen one in its place. This is a medium sized supermarket.
