Not me but in one of the neighboring towns where I grew up. A librarian was using her job and location in the public library to escort herself. The library had a second floor; more like a loft area. This was for microfilm, microfiche, references that had to be controlled or forbidden to be checked-out, etc. So the place was usually quiet but more importantly, it was glassed off so less sound. Customers would apparently go up there and ask her for a certain reference. How they came to get this reference or their meaning I do not know. But she would apparently lock the door going into the area and they would conduct business right there. She also apparently volunteered to stay late after hours so she could use the entire empty building to host multi-partner get-togethers.
Not a librarian here, but the weirdest thing I witnessed was a 17-19 year old who knew where the bathroom was walk around and find random area to piss in. Not entirely sure what was going on with him.
Way too many men looking at porn.
A condom and wrapper found where teens had been sitting all night. Didn’t appear to be used, thankfully.
A teen video chatting with much, much older men on a library owned laptop.
Guy would call the library at least a few times a month and ask for definitions of sexual or other explicit terms, but only wanted female staff to answer. He got off on hearing women describe the term.
One guy called constantly asking for shirtless pictures of Justin Bieber and wanted us to mail them to his house. We didn’t.
Old people farting. A lot. Like every day I hear an old person just rip a fart and act like nothing happened.
Homeless and/or housing insecure people sleeping in the library.
Guy who owns a massive pickup and camper would sit in a study room all day. We would often find empty cans of food in the trash after he had been in there. Later realized he was using a slow cooker to make meals at the library.
One library I worked at had to install sharps containers in the bathrooms and also make patrons check out the key because so many people would inject heroin and pass out. And then throw the used syringe in the trash. Our custodian had multiple close calls with accidental pokes.
Two guys were secretly drinking beer in the study room. Then went outside to smoke and got in an argument with middle schoolers. Kids said the guys were swearing at them and were drinking beer. There were several empties in the study room trash can and more in the guys backpack. Had to call the police because they wouldn’t leave and were yelling obscenities in the library.
One time police showed up to the library and asked who called about an argument. Library staff had no idea because none of us called. Someone comes out of our large meeting room and says they called the police because two people got into a physical altercation after yelling at each other. It was a condo home owners association meeting.
I’m sure there are more but this is all I can remember off the top of my head. Also I’ve only been a librarian for 5 years.
My mom is a Librarian. There was this really old dude who would go to the library, print something out, then SPRINT over to the printer, pushing past everyone to grab his sheet, and bolt out the door. One day, my mom stopped him from immediately leaving because he had to pay for the sheets. She pulled up his records and surprise surprise, he was printing porn. What happened in your life where you’re now spending your last days going to a public library to print out black and white porn images?
Caught a guy lure a woman and her daughter into one of our single use bathrooms. Just last week someone threw up ramen noodles at a computer and had to be practically carried out because of how drunk he was. A homeless man put a blanket over a computer carousel and tried hiding underneath so he could sleep. We had this homeless black lady yell racist things at a white guy minding his own business. I find the visitations in our meeting rooms kinda weird. Especially during holidays. They will bring in cakes and presents and just spend a few minutes with their kid.
Edit: I forgot a really weird one. It was close to the end of the day, when all of a sudden I heard screaming. I looked around but didn’t see anything. The screaming lasted for only a few seconds. About 3 minutes later, I heard the noise again. I get up and walk around the computers. A guy was at a computer slouching over but was still semi-conscious. I noticed a can of air at his feet. I got security because that is above my pay level.
