I will say that when I lived up north, the UPS guy was always the same guy and was very nice and I never had a problem. Since moving down here, we get these douchbags that are jerks. Most will knock and run. I come to the door and they are already out to there trucks. I've had a couple not even knock. I saw them in the window stop and then drive away. I go the the door and it's sitting there. Is it that hard to knock and say hi?
And that is not including when they've screwed up stuff.
