Mr Doyle,
as a customer like yourself, I have noticed too that Silverprint is a quirky place.
Where else do you find such a assortment of goods, efforts in sourcing materials and advice which you cannot find in the manuals?
If they were after your money properly, they would be bankers or Warren Buffet type people.
Yes they love what they do, but also have to be profitable in order to be here and offer their services in a difficult market.
So rather than wish their demise, which you seem to imply with your reference, in extremely bad taste, to Kodachrome and Tech Pan; we should rejoice that people like Silverprint exist (2 miles from your home!), and give them all the support they deserve.
Many years ago, I was part of a commercial team. The vast majority of our customers were reasonable,pleasant people, interested in getting on with what they did best. They appreciated our services and advice.
Very rarely we had an unjustifibly difficult, unpleasant , even rude customers.
After exhausting all possible avenues to satisfy their requirements, we put in action our "merry go round" policy. This consisted in the customer facing a difference member of staff at every visit. Politeness was de rigueur, and the advice good and to the point; exept that the point was continuously on the move.
Eventually, having suggested that the clients should avail themselves of services from establishments with more charm than ours, they dropped off like bad fruit, as they should.
You have no idea how good this was for the staff morale, not to speak of the profitability of the business.
Rather than crowd the airwaves here, make images and use your Rodinal before it goes off.
