Way back in my can hauling days I got dispatched to an ice cream factory.
I got a reefer can loaded on a genset chassis. I fire up the reefer and genset and set it to temp and off I go.
Most of the guys at this can place were rookies that got their license through the company (indentured servants).
I get to the ice cream place and meet the shipper guy. He says go park over there with the other 6 company drivers until you get to temp.
I said I am at temp. He looks and says ya you are, back into this door.
I was loaded and away while these other guys were sitting and waiting.
It never occured to any of these guys to start the reefer as soon as it was set on the chassis. They all waited until they got to the shipper.
Hello, we get paid by the can!
