Mr. Professional looks over his shoulder and cooly states "It is hard to avoid in a gun shop."
Absolute, lazy, braindead BULLSH!T!!!
This guy needs an education sooner rather than later. If he won't take it from a customer, maybe he'd pay attention to his boss.
In my first CCW class the instructor made it perfectly clear that NO weapon will be allowed to be pointed at anyone at ANY time.
If we saw him muzzle someone - even with a plastic demo gun - we would immediately get our money back and the class was free.
That was enough motivation for the class of 30 or so people to watch very closely, and it never did happen in a room packed full of bodies.
