With UPS, the power of POSITIVE can change these bad habits.
There was a guy in town who had a POSITIVELY bad UPS driver. They would leave boxes in the rain two feet from the covered porch. Kick boxes to the front door, Drop wooden crates on their corners to see if they would break open, etc.
One day, the POSITIVITY bad UPS driver was carrying a medium sized but quite heavy box to deliver. Placing it down gently seem too hard, so he just dumped it. The box hit the ground and broke open. A 1000 rounds of surplus .308 flew everywhere.
The guy can home that day to find a beautiful stack of cartridges and a sweetly written apology note. Apparently the UPS driver was POSITIVELY convinced that we was going to be hunted down and killed for his previous behavior.
After that, boxes were delivered with great care (fear?).
So, as you can see, UPS drivers can be retrained with the power of POSITIVE.
