Extremely tender beef at hospital
One possibility is that the meat was cooked in a crock pot. This would make sense on a few levels. 

First, since it is a hospital and presumably they have a large amount of people to feed, cooking multiple steaks in a large crock pot at once would save time and still produce quality food.

Second, cooking the meat slowly in a crock pot (or in liquid) over the period of 10 hours will produce incredibly tender meat, especially if the steak was already of good quality to begin with. Similar process is used to produce various roasts and also pulled pork, for example, which will literally fall off the bone once done cooking.
