Toggle Switch

On the top of most automatic doors in most convenient stores such as Meijer or Walmart, there is a switch on top of the door that controls the sensor. As you walk out simply reach up real quick and flip the switch, turning the sensor off...sit back and watch as customers smash into the door as they expect the automatic door to open. Barely any people know that the switch is even there. It will cause a lot of confusion and people's reactions are priceless.
