Who chewed my meat?

Dad and Matthew and I went to Far East Taste for dinner. Dad repeated a lot of his antics from the previous visit - asking for bread to go with his soup (no Dad, a chinese restaurant does not have rye bread), insisting on ordering something else than what you suggest and trying to cut the big hunk of hard broccoli in his soup bowl which looks imminently in danger of flying across the room.

but he topped his performance tonight with the strangest sequence of thoughts. He ordered beef and it turned out to be chewy. So he proceeded to pull half chewed pieces from his mouth and place them on his plate. As the meal progressed and Dad put rice on his plate, I saw those chewed pieces getting closer to his rice and fork. Finally I said "Dad those are the already chewed pieces of steak your are about to eat". He looked at me and actually said "who would chew my meat???" He was incredulous that someone would do that to his food.......
