The four times someone has had a gun or claimed they had a gun in my store to rob us, they weren't in the store long enough to see whether others were armed or not. I have been fortunate enough to not be there, but we do all watch the footage. The criminals that come in our store do what they have to do and run. My location has a reputation for positively IDing and deterring scum. Rarely in the last few years has many of them been in the store long. And I talk about all forms of criminals in my store, not just armed robbers. But, the ones that have robbed us, haven't spent my time in the store and they are always intent on the cashier and not what is occurring around them.
