UPS and FED EX delivery drivers

I don't have any problems with UPS, USPS, or FED-EX drivers. The Amazon Prime drivers seem to be OK, but putting a package in front of the screen door you have to open seems a bit ridiculous. My dog didn't like one of the Prime drivers... and he loves everyone else. I've learned to trust dogs over people and I haven't seen that driver again, so I'll bet they are no longer with Amazon.
