Sir – Waitrose is wonderful! With delivery orders on the books and icy weather condition so that customers are trapped in their homes, do they cancel all deliveries?

Absolutely not — they phone to warn of delay, they put two drivers on board (with plenty of shovels) and beaming with good humour they turn up at your door having cautiously made it through the ice and snow.

Now that’s what I call service with a smile!
