...My two favorites call for emergency entrapment..while you are rushing to get there ..fifeteen minutes later they cancel the call got the people out ..no service needed till am..or better yet they call and all the elevators are not working..unless there is a power problem or fire service issue..you know this is only a ploy to get you there faster..how many times do you fall for this one...definitely not worth risking your life racing to a call..
