Went to my bank, Wallgreens, and Arbys for lunch. Only had a single encounter.
My bank has signs posted so I left my firearm in the car while I ran in. Came out and started to get into the car and the following happened:
SG = Security Guard
SG: You on duty today?
SG: Is that concealed?
SG: You know you can't carry a firearm inside the bank. We are....
Me: I didn't carry anything in the bank, I left it in the car.
SG: Oh, I'm sorry I accosted you. I have had 4 people open carry in here all ready today.
A very pleasant conversation ensued and ended up with me giving him some OKOCA brochures. Turns out the security guards have asked the bank to remove the signs to no avail.
