"Also, I consider it an act of discourtesy to the proprietor and fellow customers to carry a firearm into a place where the proprietor has clearly indicated that patrons with guns are not welcome. It's more than a question of just being able to "get away" with a simple trespass charge, it's just common courtesy. If the store owner or manager doesn't want me with my firearm in that establishment, I don't go inside with it."
I guess I'm just one discourteous S.O.B.
