Yeah, worked at a one-hour photo store when I was a teen. "Put the screen down" was the signal that some "amateur stuff" was about to come down the print out-feed (a kind of curtain/cover would hide the prints coming out from the general public). (Kind of wild that people's photos coming out of the machine was something of a feature the store made readily visible to the passersby in the mall where the One House Photo was located. Privacy, what?)
And though I wasn't one of the techs that made the prints, I do seem to recall they would spin off dupes for their own private collection(s).
Yes I think I remember a time when you could see the Walmart photo center one hour prints just spool off the line and collect in a holder. Times were so different back then.
