Popped off Cabinet door when pushing slide out????

During the inspection of our first new trailer, the salesman was opening the slides and one of the upper kitchen cabinet doors was ajar. The slide snapped the door in two lengthwise! One side stayed attached to the cabinet, the other side flew across the counter, barely missing my head. That gave us a very healthy respect for the power of hydraulics and we always check for anything in the way of a slide before opening them!
