A fire alarm was set off. As everyone exited the building commotion erupted. I heard screaming. When I got close enough I found one of my co-workers (a obese adult of very large size in real life) shirtless being chased. The person chasing them was a former employee whom hadn't worked there in over a year (at the minimum) with syringes on his hand like Freddy Kroger. It felt strange to see my obese co-worker running because of his overall massive weight it wasn't physically possible to maintain the speed he was moving.
