You hope that is their intention. Do you really know? You know nothing about this person.
Good point. But they don’t know you either.
The first time a dog bit me on the job, I was inside a customers house. It was a German Shepard. Luckily a smack between the eyes with a screwdriver was enough to stop him. But what if he continued his attack?
I have the right to protect myself anywhere anytime by any means possible. That’s why the gun is concealed and the customer does not see it.
