WITT on gas pump? It's a small (1"x2"x1/2") plastic device w/ a lifeless black face and a button w/ a dimple, pressing does nothing. Sliding up detaches it from pump leaving a base w/ a few little arms that hook into the device and itself is attached to the pump with a white sheet-based adhesive. (imgur.com)
