Take a number
If you have a complaint or a question regarding this person’s work, we suggest you keep it to yourself, you don’t want to blow up. We guess that this employee just had enough of everyone’s questions and wanted to be left alone, they were up to their necks in high stress.
We don’t really know what forced this person to be pushed to the edge, but we hope that this grenade was never put to use. Imagine being so done with dealing with people you need to get a grenade to fight them off. Maybe it’s time to find a new job.
