Sure.
If it's an employee selling a gun, why is it inside? I suppose the answer will be for security. I've never been to (any) JAX so I don't know how safe the parking lot is. But if this is the case, you have employees with EBRs working at a place that, again, very publicly decries EBRs.
If it were a consignment being returned, if I were the customer, I would expect to walk into the store and get my rifle back, not deal with an ununiformed employee in the parking lot.
Note, I never suggested calling the cops. I said it was probably legal. But after JAX's stance on EBRs, doing any kind of dealing in EBRs out the back door definitely stinks.
