Welcome to the club! Me and a friend met at Golden Coral one day when I was still in my 40's. The girl at the cash register asked, "Are either of you senior citizens?" My buddy, without missing a beat, said, "I am not but he is (pointing at me as he said it."
I got the ticket and low and behold, there it was, the senior discount. LOL
Oh, by the way, that is what you get for rubbing it in that you were riding around in air conditioned comfort while we were freezing to death over here!
