Not really, sometimes it's just the nature of the environment you work in.
When I commenced employment at the second law firm I worked for, and it was apparent I had some experience in security training and martial arts, I was told that my office was one of several that had a 'buzzer' in it. I was told that if that buzzer went off, I was to start moving towards reception as quickly as possible because it meant that an angry family law client had forced their way into the offices.
This was a medium tier, reputable firm.
I forgot to mention security guards! But if you're not actually employed as a security guard, then you probably should not be grabbing any crazies.
