Was taught to do it as a kid and have rolled sticks ever since. I do it on the counter or floor of the store before I pay for the things. In fact, don't think I've ever bought a pair of sticks that I haven't rolled. Even when I was getting sticks made for me and bought them in bulk, I rolled them before putting them in a stick bag.
