I spent the last 2 summers building skateboard parks in NYC w/itinerant crews from other places. Nobody paid the $13/pack unless push came to shove. Everyone was rolling them, which bothered me because it slowed us down and became a point of contention with non-smokers.
They obviously didn't know what they were doing. My husband can knock out a full pack in less than 10 minutes. Even I can make at least half a pack in about that time, and I am no where near as proficient as he is.
