You run a 1-hour photo lab. Customers come in with film, you take the order, extract the film, run it through the C-41 processor, print the negatives, cut & sleeve the strip, and file the finished envelope so they can pick it up.

Hours: 10 AM–6 PM. The store starts the day closed — flip the OPEN sign on the front door when you're ready to take customers.

End of day: sit on the back-room couch to sleep and tally up. Anything unfinished is force-closed (filed orders pay grumpily; mid-pipeline pays nothing) so try to clear the boards first.
