I have already contributed to this thread, when I mentioned the subject at work my colleagues jumped on me - I work for a better style of supermarket as a internet shopper and help out on the tills from time to time. My colleagues wanted me to put their side of the problem forward. Rude Customers , of whom we have on a daily basis. A few contributions include: when the cashier greets the customer they are completely ignored, customer on mobile phone on unimpotant call, the whole transaction is conducted without any indication there is another person opposite you who would appreciate some acknowlegement. If your card is declined it is not the cashiers fault. Please hand your money to the cashier without a]licking it first or b] plonking it down rather then hand to hand. Don't snatch your change back as you might scratch the cashier several of us can attest to that. Don't let your kids use our wide aisles to cycle along,scooter along, roller skate along, use to race against their friends. Don't give your children sweets, crisps or drink to shut them up and then hide it so you don't have to pay. We do see this your know. I was given a list far longer then this but sad to sorry rudeness seems to be a two way thing nowadays.
