Letter: Errors at the till

Sir: You report (28 August) that "One in six supermarket bills have the price wrong". For the past two years I have been regularly checking my till receipts and either returning to the store or writing to the manager when there has been an error (unfortunately never in my favour).

You are right to blame the speed at which items are scanned. Last month I learnt that the supermarket regularly ran a competition to see which cashier could scan the most items per minute. Small surprise that errors occur.
