You know, you can make a contest out of most anything. Americans in particular like contests like this one. Introducing a competitive spirit into everyday work quotas is how people get fast in the first place. If you’ve never looked over your shoulder to see if the next guy is going faster than you are, I feel sort of sorry for you. You always run faster in races with other contestants, not just a clock.
I was a mason tender for a guy that would have put all these guys in the shade, left-handed. He had one weakness, though. Me.
