Be glad it just gets on your nerves! In California (USA) a man purchased $600 (yes, that's dollars) of groceries. Apparently, he was doing a self--scanner and he was in a hurry or something and failed to pay for items worth approximately $10 (not that much). They arrested him and charged him with a misdemeanor.Do these get on anyone else's nerves. Particularly when the item won't scan. In our local Poundland they had a machine that said thank you for shopping in Poundland in a elvis soundalike voice. Most are card only too which is annoying as it's just another step to killing off cash.
