Incident in a Restaurant

Once, when I was by myself in a restaurant, I ordered steak, even though I have trouble cutting meat. Several men in business suits at the next table began talking, loudly enough for me to hear. In fact, they probably meant for me to hear; they probably wanted to embarrass me.
"Look at the way she cuts her meat."
"I guess nobody ever taught her proper table manners."
And so on.
Well, I was embarrassed. More than that, however, I was just plain mad!
I turned to them and said, "Excuse me, but I am awkward cutting my meat because I have a slight physical disability and poor co-ordination. YOU have bad manners!"
