There's a reason I hate going to PC World, and yet like a dog returning to its sick, I continue to do so. Today's visit illustrates why I reckon its the chain store with the worst customer service in Britain. It's staffed by acne-ridden, monosyllabic teenagers with barely a GCSE between them, few of whom know anything about the products they are supposed to be flogging. And its computer system seems to hail from the time of Noah's Arc. It makes BBC Basic look state of the art.

Anyway, why did I end up there today? Because Olly Grender, bless her heart, finally persuaded me to buy an iPad after she showed me all the things she did on hers. She has a lot to answer for. So, I've decided to go over to the dark side. I started to order one online from the Apple Store, but then thought, bugger it, I want one and I want it now, so off I trolled down to PC World in Tunbridge Wells. Normally when I try to buy anything from there, there's some sort of problem. Usually they haven't got what I want in stock, but today I thought I had struck lucky, as yes, they had a 65GB 3G iPad in stock and also a Vodafone SIM to go with it. Excellent, I thought.

Then their computer system seized up. Five minutes later the assistant started asking me my marital status. I never quite know how to answer that one. They don't have a box for 'civil partnered'. So I said 'married'. He then asked how many credit cards I had. Er, none of your business, I said. In any case, I haven't a clue. Why do you need to know that, I asked. I should have known the answer. The computer says so, said the nerd-geek. He then told me all the other personal info they would require. This was all to set up a direct debit for Vodafone, nothing to do with PC World! I have never had to give any of that sort of info to Vodafone, so I am damned if I am going to give it to PC World, supposedly on their behalf.

I told them exactly where they could shove their iPad and have just come home and ordered it via the Apple Store. Which of course I should have done in the first place. Lesson learned.

How does PC World manage to stay in business? Because I am buggered if I know.
