It's the same down here, though we have don't have Tescos. a few years back there was a 1 Hour service (Process, scan to CD/print) in almost every Pick 'n Pay, Game and Clicks (South African Chain stores) now almost none. The few that are left (not in my town) give crap results & have rude staff.

Where I live there used to be four labs, now only one Kodak (with extremely rude staff) and they told me upfront "look this will take 5 days and your results won't be optimal" - they just don't have the "traffic' anymore. My only recourse for color are the pro labs (which are far away) - at least I can do my own B&W.
