The delivery man was walking up my front sidewalk with a package. I was walking down my driveway and called out to him, "Sir, Sir." He did not respond so I called out "Sir, Sir, from UPS." He dropped the package at my front door and continued into his truck. I told him, Sir, I am talking to you and he responded "Shut Up" and drove off in his truck.
I wanted to inquire if he needed a signature and also wanted to immediately take the package in hand because it was an item of value.
It appears that UPS needs to revamp its training of drivers.
