On holiday in the Florida we walked to the gated entrance to the community to ask whether delivery drivers got access or we needed to pick it up at the gate. The way they looked at us, you would think we had two heads for arriving on foot.
Fixed that when I asked if he personally called 911 and when he said no, "So, before we make this a lot more formal, are you understanding that you are now obstructing emergency services personnel in the performance of duty?"
