I'm with worker 11811. If a retailer isn't holding stock of what I want to buy or compare; if they can't talk about how it works and its good/bad points in a knowledgable and cogent fashion; and can't treat me nicely instead of viewing me as some inconvenience that's wasting their time, then for me it doesn't matter one jot whether they exist or not. It is for the retailer to use their ingenuity and business acumen to arrive at ways they can attract customers in a world where they are doomed to be more expensive. It isn't for the customer to forgive them their failures. If the retailer thinks he can do that whilst offering worse service, less information, less stock, and worse prices, then best of luck with that.
Meanwhile it was a telephone /internet photographic seller who maybe ten years ago realised in the course of a call with me that they'd messed up my film order and had missed the post. I was due to travel on an assignment the following day. They got in a car and drove nearly 100 miles round trip to get me the film on time. I just can't imagine any retail outlet of my knowledge doing that. I'd like to think that this outlet got enough business from me after this event to have made their gesture worthwhile.
