I worked in a minilab one summer. The Noritsu printer had, IIRC, a +/- 1,2,3 override for R,G, and B. So if you saw a head over a big blob of green (someone wearing a red shirt), you'd hit +2 Red to override the printer's attempt to "balance out" the colors.

We never got any 'interesting' stuff. I suspect people would prefer a bit more anonymity than you would get from a 2-3 person shop where the person who printed your stuff might also be the one ringing you up for it.

My father owned a photoshop that was a one-hour lab for the last decade of its life. I worked for him throughout my teens and have printed many thousands of photos. I've seen interesting stuff. Most of it is pretty boring.

Not only did we get interesting stuff, but we would routinely print a few extra prints for a photo album we kept in the back.
