No we didn't have Fotomat so far as I recall. We had Kodak film kiosks in stations and so on but no Fotomat.
Some Asda stores still develop C41 in an hour... for £2. I had good results for a few years but the last couple of times they got sloppy and there was plenty of dust, so I've gone back to home developing. It's important to support supermarket C41 because head office are keen to replace those Fuji wet machines with something new and digital, but there are limits. I'm not sure the operators think film care is a good use of their time anymore. There's still quite a market for disposable wedding camera processing, they tell me. Last summer the one hour service became a few days because they had a mountain of throw away camera film to work through.
I went in one time and asked a chap behind the desk if they still did film. He said yes we do disposable cameras. I said 35mm. He said disposable, sure. I said 35mm. He couldn't believe people still shot film in cassettes. Another time a lady was having prints from her smartphone made, and the machine was playing up. I said you want to use this stuff and dropped a handful of colour negative film on the desk. She thought it was amazing the staff knew what to do with it.
