I just thought of another advantage. I can sometimes talk my way into what I want with younger guys because you can tell they're like "OMG, this is like arguing with my mother!"
One year at Quilt Festival, I didn't want to park where the guy directed me because I wanted to be on the end of the row. He came over and told me to move and gave up after a few minutes of agruing. The next day he just directed me to a space on the end of the row.
