Why waste the time of indolent, ignorant shop assistants that hide from customers and are about as unhelpful as they could possibly be without actually undergoing specialist training for it? Why indeed? I couldn't possibly think of a reason. I never bother with shop assistants because with a few notable exceptions I've never found them to be much help or indeed interested in being much help in local clothes shops ( think NEXT, Monsoon,etc) M&S have very good assistants, polite and helpful but there's nothing in there I'd be seen dead in, so what would you like me to do? Monsoon certainly expect people to try on in shops and buy ( from them) online, but I'm really not going to start crying into my wine over the fact that I buy Monsoon dresses from Ebay after I've tried them on in store. This whole judgemental nonsense is pretty petty. You shop your way and I will shop mine.
