So this happen on my previous workplace. I worked there for 4 years and quitting was the best decision I made while was there.

One manager/owner there was the most toxic, piece of shit, disrespectful cunt I have ever worked with. The type of guy that comes in and every person's productivity goes down in a heartbeat.

As he was a owner he usually came in later. This one morning it was 11-ish and a meeting with a client was happening and it was an open space.

He comes in.
He puts his laptop down.
He sits.
He screams of the top of his lungs:
- WHAT THE FUCK IS THIS?
- ANTS ALL OVER MY DESK!!!
- I CAN'T WORK LIKE THIS.

He leaves for about 30 min.
He came back with a can of spray, and literally intoxicated the office and everybody had to stop working.

And there you go one of my last place's beautiful stories.
