The 62 yr old was picking the best parts of the salad ingredients out. If that happened in a regular buffet, I suppose you could ask for a refresh of salad from the manager, and get it. In there, food was probably at a premium and a serious matter worth fighting over. The 62 yr old should have known better, but for him it was not a survival matter, but one of luxury and extreme selfishness...what he may have been used to in the active world of everyday activity.
He doesn't belong in there, God forbid any of us ever end up in a place like that.
