At least that is a line I use occasionally when a waitress is asking me if I want dessert after my meal. Then when the check is brought out I show a picture and say, see I was not kidding - that?s me, Haha. So I am on the road and did that tonight and my waitress loved it. That happens fairly often - give it a try sometime. They are often quite surprised and amused by it in a happy way.
