Meh..dont have that problem at my job.
I stronlgy encourage all my staff to do the following:
1. Get a LTCF
2. Get trained
3. Carry it to work
So far NO shootings beteween the staff
No staff shooting the clients, although a few deserved it
And amazingy no daytime robberies either when the staff complied with this request.
Stunning aint it???? rofl
