I've done that a couple times. I still haven't found a good place to put that towel. If I leave it in the cart (I do most of the time), it's useless to help clean off the ball. If I leave it in my pocket, it feels uncomfortable. If I throw it somewhere off to the side, I will forget it. Then somebody will steal my towel that cost me $1 and I will have to bug the course about it for a week.
