What difference would it make if there were 15 drivers or 150? The rides are one on one and any on car or center manager/BM worth his/her salt can find ways to improve any driver's routine, whether the improvements are minor tweaks or a total refresher course on the 340.That's funny.
Maybe in some little 30 driver.... podunk center.
Not in the real world.
Our mall driver had a part time job as recreation director of his hometown, which required him to get done fairly early. Cover drivers had a very hard time covering his route as they were also expected to get done fairly early. Turns out he used to call most of his pickups to see if they had stuff going.
