I suppose if you look at the statistics then the majority of your customers are reasonably law abiding, don’t pinch from you or abuse your staff. But, yes, it’s time for another warning.

Paresh Pandit, who runs R&K News in Leicester, wanted to share his experience. A customer, unknown to him but looking perfectly respectable, came in and asked for £10 to put onto his Orange card. When this was done he said, ‘Oh, I want some milk too. I’ll just nip out and check with the wife whether she wants red or blue top.’ You know what’s coming. He was never seen again.

Paresh rang the Orange helpline, which couldn’t or wouldn’t help by cancelling the credit even though he rang within the 10-minute time limit for cancellations. As he had the man’s phone number on the top-up record, he also rang the police and handed on the number.

The police did ring the bloke up but he said it wasn’t his phone and didn’t therefore want to pay. You can’t prove ownership of the top-up variety of mobile phone, so Paresh is left kicking himself for not taking the money upfront and wondering how long, at 4% maximum, it will take him just to make up the tenner lost. Since you can’t always tell the chavs from the chaps, it has to be a rule that you always get the money first.
