In that particular snow storm, I was trapped on an elevator with an electrician for over an hour! It was at a building that was under construction but was nearly finished. the Elevator tech had just left and the motherboard in for the elevator fried. We were trapped on the top floor so opening the top hatch got us nowhere. We were screaming for help but construction workers were running saws on the first floor (only two floors) and no one could hear us. The snow had started about the time we got on the elevator. The other workers knocked off early for fear of being stranded by the snow and the sit just got quieter and quieter. Cell phone calls to my office were to no avail because they had all gone home early as well. Through an elaborate series of phone calls, I was able to get someone at the main office of the construction company and the contacted the Superintendent. The Elevator tech had already left for the day and was very reluctant to return. After a very long wait we were rescued and when we emerged from the elevator we were shocked at the blanket of deep snow that had not been predicted.
I've been stuck on a few myself. Only one I could not get out of and that was because the door actually jammed shut. I had to wait on a guy I worked with to come in and get me out. Lucky for me he lived nearby. Usually I was the rescuer to ones trapped too as I was the on duty maintenance mechanic. I know how to get in and out from both sides and carried a flatheat screwdriver to trip the doors open on the lobby side.
