Wonder why?

It snowed last Tuesday. So, the state, as is its custom, paid 700 private sector snow plow drivers the agreed to rate of $120 per hour to plow state highways. But because last Tuesday was Lincoln's Birthday, a state holiday, the drivers got another $13 an hour in holiday, or overtime, pay. These were not even state workers.
