Competitively priced, good selection, good offers, good for families, very good parking, found in decent out of town locations to good for traffic, ranges from 'basic starter' to many of the brands you might find in specialist stores, great clothing range.
You wouldnt go to a B&Q and expect to see a qualified plumber or brickie on every isle any more than you would expect to see a qualified chef next to the chickens in Asda. Why would you therefore expect to see a qualified climber or moutaineer in GO. At worst they are there to direct you to the appropriate isle. At best their profession will also mirror their hobby.
The staff are trained to a certain level on loads of products, often as a first or second job. Lower you expectations folks - you get what you pay for.
If you want specialist knowledge then go to a local specialist retailer or Cotswolds at a push - Nottingham is pretty good. Thing is, you will complain when you have to pay that slight premium.
