The irony of all this is that for the past few weeks I have had tennis elbow and can’t control the fingers very well on my right hand. So when a shop assistant asks me to type in my ‘four digit code’ and then turns away, I have to ask them to key in the numbers or risk making a mess of it using my left hand. This straightforward sale turns into a mass of niggly problems for the assistant, who can’t possibly know what the legal position on this is. Shopping etiquette.
Last week, I even had to ask the man behind me in the queue for the cash machine to type in my secret code. He wondered whether it was legal to do it.
