BAN Paper Coupons
They done good by no longer handling a customer's own reusable bags.
I was at London Drugs and the cashier handled a customer's really dirty coupon and then handle my purchase without disinfecting in between.
I complained and the cashier was shocked and didn't know what to say to me. I not complete the purchase.
Maybe someone could invent a coupon app or something similar, but with COVID 19; the paper coupon should not be used.
