I was just speaking to a friend of mine about this today. He's got a bit of cash to burn and often pops into the bass shops in London for a quick snoop when he is down there. As soon as I mentioned the Bass Cellar he seemed to sour slightly, and told me he'd been there before but was quickly put off by the fact that the staff didn't seem interested in entertaining him as a customer. And he's a bloke of nearly 40 with a smart look, basically a walking wallet, if they took the time to talk to him.
But he likes good customer service, and obviously felt that this lot, who seemed "bored and disinterested" and seemed unwilling to engage in conversation, were not worth his timr or money. I really must go there to see this for myself.
