It is always sad to hear the closing down of high street labs, but it's a sign of the times.
As some of you may know I own a minilab in rural Ireland. In the late 1980's and early 1990's our small town (population 19.5k, county 65.5k) had 4 onsite processing minilabs. One photo chain store with Agfa, one photo independent with Kodak , one pharmacy with Kis/photome and ourselves a photo independent with Fuji. Even back then the quality of some of the labs was very bad and it gave everyone a bad name. I must admit that while our quality was spot on (we did all the usual test strips etc) the Agfa lab was hard to beat. But the Kis and Kodak were very badly run and the quality very poor.
Those poor quality labs were basically installed because minilabs were the new cash cow. Photo processing knowledge was not top of the agenda. And of course when the market is in downturn they are the first to leave the market.
I believe there is a return to printing photos (digital) and I have seen an increase in film processing in our lab. Having said that, we actively promote film processing and film cameras and film sales. It has become a niche market. I know instore can't compete with online regarding film sales etc, but online film processing (mail order) is 75% of all our film processing.
Maybe smaller companies can adapt quicker to a changing market and that is their strength compared to the large chain store.
The down side to Boots closing 2/3 of the labs is that people think film is really gone, dead and buried.
The up side is that there is more film for me to process

It's just a matter of getting that info out there and Google is our friend.
