I went to the Durham Dragonville store to buy (a) a canister of gas for my brazing torch and (b) a tube of superglue. Arriving at the checkout, the young lady there told me that she, being herself less than eighteen years old, is not considered responsible enough to sell goods that may not legally be sold to anyone under that age. I offered to show her ID, but no; I and the rest of the queue at the checkout had to stand and wait while she fetched another assistant old enough to to tell whether I am over eighteen or not. (I am seventy - and look it). This is not an isolated irritation; if it were, I wouldn't be moaning about something so small. But I've lost count of the times I've been annoyed, frustrated, delayed and disappointed at B&Q, and treated with what feels like studied discourtesy. I still go there to buy small items, because it's conveniently near to where I live; but, honestly, the incompetence with which the store run is almost laughable, and the attitude and ignorance of the staff is deplorable. Some of them - not all; there are honorable exceptions - deserve a P45 straight away. Who the hell says, in answer to a customer's question (and I quote): "Dunno, mate; I only work here"? I don't wish anyone ill; but I can't see B&Q surviving as a business much longer unless they buck their ideas of efficiency and customer service up pretty considerably; and they really don't deserve to.
