I worked at Papa Murphy’s on and off for about three years and whereas we didn’t bake the pizzas, we had to stretch out the cold crusts. So, I learned that way. Lots of practice and torn crusts later, I did it. Since the only two choices were ‘not worth doing’ and ‘worth doing’ I chose ‘worth doing’ because I believe that you should experience as much as you can in this life that is far to short to begin with. Good luck to all who want to learn to do this one day. :D
