Stress is when you're at a stop and a child/children come running out looking for a package thier mom/dad said was coming only to scour the truck and not find it, only to tell them someone may or may not be by to deliver it today.
What's even worse is when you get to your first pickup and see it laying there, only to find out it's been there for 6hrs and the rookie driver failed to scan it in as a misload to take it out of your board.
Then you run back to the aforementioned house, only to look like the biggest idiot in the world as you pop open the back door and all they see it their box surrounded by empty chrome shelves.
No stress, "Hey there! They found your package and I got them to let me bring it to you. I wanted to make sure it got here."
