Worst on the job experience you've ever had?

I still think about this fairly regularly and have to laugh about it now, so I figure I'll share.

Over the summer I had a PWM internship at a family office, I got the job through my buddy's mom, I've been best friends with him all my life, she knew how hard I was working towards an internship so she gave me a shot. I was very grateful for the experience but I got roughed up pretty bad towards the end.

My buddy's mom was on a meeting for some time, I needed her birthday to complete a release of information from our broker dealer. I decided to open her portfolio to get her birthday. I (very stupid I know) left the tab open while I left to use the restroom for a moment. In the mean time she stepped out of her office for a moment and saw my screen.

Later that day I got a phone call from her being understandably angry. She figured I was snooping to see her portfolio's worh (also very understandable). I explained myself and apologized, she reprimanded me but understood, and that was that.

The following Monday I go out with my other supervisor for lunch, and while I'm there I get a phone call from the President of the company who was out of the office that day. He sounded extremely angry and told me tomorrow we needed to talk as soon as I get in.

Fast forward to tomorrow, I walk in at 9am to see all three of them sitting down in my office. I start getting interrogated, accused of going through their client list to try to sell the names to a buddy of mine working at Equitable (who they knew worked under one of their old supervisors when they worked there). He proceeded to ream me out, accusing me of all these different things I had no intention of doing, threatening to report me to the SEC and take legal action against me. He used his best knowledge of psychology to try to make me admit I had done this (like a cop lying and saying they know you committed the crime to get you to confess). I (make fun of me all you want) am sitting there, trying not to start sobbing with tears running down my face, choking up while trying to talk. I'm trying to explain through my tears about how I would never try to destroy my best friend's (and college roommate's) livelihood. My supervisor who I worked very closely with all summer is sitting there white as a ghost, while I get reamed out about not using a vpn and logging from home, which he had authorized me to do.

The president ends up going on rant about it, and tells me a story about how someone he knew got his internet network hacked  by someone so they could download child porn, and compared the situation to that. I was in utter disbelief, never got an apology even at the end of the internship. 

Every day for the rest of the summer, I was on the verge of having an anxiety attack the entire time I was at work, so severe I had to have my anxiety meds changed because of it. They ultimately knew I wasn't lying, but still never apologized not even once. I look back on it now and laugh at the absurdity of it, but I still feel angry that I let myself get treated the way I did. Looking back, I should've walked out that day and never came back, but didn't want to do that to my best buddy's mom. Total disaster and I knew from that point on I'd work on getting an offer somewhere else, despite being invited to come back next summer.

Can anyone top this? Let's hear it. 

For some comedic relief, there was one day in the middle of the summer (we were in a multi level office building with different companies) someone had shit in the middle of the lobby. There was shit leading to the lobby bathroom, the second floor, shit in the elevator. Truly one of the funniest and most disgusting things I've ever witnessed. What was most priceless was having to come back from the bathroom and tell my boss there was shit all over the floor. It wasn't me I swear.
