I can't even begin to recount the items found after shows when I headed up the maintenance staff at a 20,000 seat amphitheatre many years ago. From condoms (used and unused) to bags of illegal substances (which I swear were always turned in) to couples under blankets, panties/bras (onstage and in the audience), people passed out and so on. It was an adventure every night! And that was just the house, the restroom buildings and parking lots could sometimes be just as interesting. Then there was the time we found the entire fruit platter from catering the night before under a couch cushion in one of the dressing rooms.
Site surveys of old spaces for renovation and restoration projects are almost always interesting. I remember one old municipal opera house so full of asbestos that was falling off the walls and ceiling that we had to perform the site survey wearing full clean suits and respirators, yet it was obvious that several homeless people had recently been living in the space.
I also know of many newer theatres where people years from now will be wondering where the antique soda cans, food wrappers, etc. came from that got left on top of ceiling clouds or beams or inside walls during construction.
