Someone forged a check from my business account. Not a huge amount, $8,000, but now the fraud department of my bank has frozen all of my accounts because they have to prove it wasn't me who did it. I've been at this bank for more than 20 years, never had an issue, but now everything is locked down. I'm being punished because some douchbag committed fraud pretending to be me.
The up side is that I'm pretty sure I know who it is, I have contacted the police and filed an affidavit with the bank. I don't care what the legal costs are, I'm going after this asshole.
Obviously not the same thing, but when I was 19 at the third job I'd ever had (gas station, with bottom of the barrel people), a guy forged my name on a lunch receipt so it'd be expensed to me. It was like $10, which was a lot to me in 2003. I went to management about it and raised a ruckus, thinking they'd look into it, but instead they let ME go because "it seems like you can't get along with people here".
Previously I'd had a few minor dust ups over misunderstandings. Like while a guy was outside pumping gas, his wife called in. I said he was busy and to hang on a few minutes, and that turned into her getting angry that I had put her on hold instead of going and getting the guy, then management heard that I "was rude to someone's wife".
Then a similar thing happened where a really young guy's mom called in asking for him, but he'd just left to drive around with some friends (yeah, while on the clock). Told her he wasn't there and I wasn't sure where he was but I'd let him know she called. Turns out she barely spoke English so she misunderstood and thought her son was actually missing. She got off the phone and was frantically trying to reach the kid and almost called 911, then chewed him out later for walking out of his job and disappearing. The guys at work all thought I told the mom he'd walked out on work and gone out driving/smoking, when all I said was that he wasn't there. Then management got irate that I'd caused someone's mom to get upset, plus the kid in question no longer spoke to me.
So between those two "incidents" (which were funnily enough both me answering the phone and women misunderstanding me), once the $10 food heist happened the manager just didn't want to deal with me anymore.
Sad thing was the station was owned by friends of my mom, which is why I went there at all, she thought it'd be good for me to work for some decent people. Their daughter ran most of the operations and she was in thick with the employees so she was quick to get rid of me. Then the owners, who only knew what their daughter told them, signed off on it, and they and my mom never really ever spoke again after that.
I've got a few more young adult job stories where my likely social awkwardness at the time caused me to get in trouble or outright get the boot over spurious reasons, and most of them are rustling. I could post the others too. Suffice to say I really should have just gone to college on time instead of waiting seven years and working odd jobs in the meantime.
