Curry's - why is their customer service so awful?

If you remember, Bev tried to get a pair of Dr Dre headphones in Curry's but all they would sell her was a sealed box.  She finally bought a pair in HMV after being served by a very competent sales person who let her try the headphones with her iPod.  Anyway, you would think she would know better than to give Curry's a second chance, but that is what she did at the weekend.  They had the Asus Transformer Prime tablet, but when she asked if it was in stock, she was informed that it was not, though if she fancied a drive to Oxford, they would probably have one in that store!
Does Bev look stupid?  Why would she drive to Oxford to get one when she can order one online with no delivery charges?  Do you know how much diesel costs these days?  So, Curry's lost yet another sale - this time to Amazon, who delivered it promptly and for free.
OK Curry's, don't blame the loss of sales on online stores like Amazon - look at the poor service you offer your customers and ask yourselves what you can do to improve it.  It's not rocket science - be knowledgeable about your products and stock, don't just say "if it's not on the shelf, we don't have it", and offer to get product from other branches to satisfy a customer request.  Be proactive!
And is Bev loving her shiny new gadget?  Do bears poo in the woods?  Of course she loves it - it looks gorgeous in its subtle champagne colour, it is functional in that it is a tablet but with a keyboar / docking station, which turns it into a 10-inch notebook, and it is fun!
