As a note - the OP had enough time between being asked to leave and the first physical part of the incident to pull out his phone and make a phone call. That would have been time better spent simply leaving.
As to the rest, it sounds to me as if the OP caused a ruckus in a convenience store, then refused to leave when directed to by security. Security proceeded to do what they do, which was remove the unwelcome trespasser from the building.
