Depends. Had a client pull a knife on me once, and another dragged me around the facility for an hour while he tried to break down a door to "kill" another client because he had stolen the change from a $5 Taco Bell gift card.

The other incident being was a coworker harboring one of the fugitive kids at her house with her like....6 children while her husband was away in Nebraska for work. Randomly saw her in family court a year later while I was working another job, hopefully while her husband fights her for custody of the kids...

That time the food cart pod exploded:

Not a fun story but new CEO comes in, pricing structure heavily modified to be more aggressive towards bringing clients into our ecosystem of products, we lose a whale of a client, 7 percent of the company is laid off including the newest guy on my team,and then magically acquire new responsibilities for the same pay. Capitalism baby.

That's complicated to answer in my case, as nobody gets along (I'm one of the few people with a relatively stable work relation), so there's an incident everyday, though there are also occasional ones that stand out a lot. I for some reason have a lot of bad rep without any actual cause for it and remember people storming into our operations more than once and demanding I be exiled from the place. There are two types of people in this situation whenever it has happened: those who are almost about to oblige and fulfill their wish, and me who calls authorities and ends up dealing with the situation before they can do so before everyone just forgets all that happened.
