I do have some sympathy for the drivers though having worked as UPS driver back in my younger days....
they time motion study you to death and expect x number of packages delivered in 8 hours without taking into account traffic, lack of parking places, ferocious large dogs with big pointy teeth , even more ferocious itty bitty dogs with really pointy teeth, lack of building/house numbers, locked gates, lonely old ladies who hold your signature pad hostage while telling you all about their grandson in California who is so thoughtful and never forgets to send a present to his grandma on her birthday even though he is all the way across the country but he is smart as whip that one, smart as whip, and doing so well, but of course everyone expected it ever since he won the science fair in first grade, only six years old ,and won best entry in the science fair, not just for the first grade, mind you , no for the whole school, and they had big kids in that school , 6th graders some of them , and he won best entry , smart as a whip that one, the big ones didn't like it one bit, not one bit , being beaten but a little boy like that, but he was smart as whip, and he worked so hard on that, you should have seen his little face, so proud, well we were all so proud of him but of course who wouldn't be , I think I have a picture here of him standing next to his experiment with his ribbon, why don't you come in for a cup of tea and I'll just find that picture .....
