One way to help get rid of them is to go to store management and tell them that some folks are interfering with you getting in to the store. It works. Prior to the last selection we were approached by some asshat with a clip board and some sort of sheets of paper working for a subset of OFA in the parking lot of the store. We complained to the head cheese in the store and they had the person escorted off the property.
Are they demanding single-action or double-action?
