Believe it or not this is an actual work question.

I work for a well known pest control company. Being a hunter, doing bird shoots inside of food factories, warehouses and grocery stores is a nice perk of the job. Even I am surprised what a regular occurrence this is. That is why I can personally benefit from having my own work air gun.

Birds regularly sneak into facilities when garbage bins are pulled out, open loading doors, and accidentally get trapped inside from other entries.
