I have a similar situation but because I'm out where I am, it's really about the individual drivers. My UPS guy is amazing. We have a long steep driveway and regardless of the package, if it's valuable, he'll either call and say he doesn't feel comfortable leaving it (since there's a trailer park nearby not that there's anything wrong with that) or he'll huff whatever it is up around the first turn so it can't be seen from the road. I'm talking big heavy packages. Brian is a good dude. That's also why he gets a card w/ cash in it around Christmas time.
The Fed Ex douche bag on the other hand couldn't even be bothered to put the ramps we just ordered on the other side of the gate much less up near the "post box" we have sitting near the gate. Apparently, he just dumped them in front of the gate. By the looks of the packaging on the ends, dump might just be the right word. Fortunately, my one awesome "neighbor" saw some activity as he was helping another neighbor and came over and picked them up and put them up around the first turn out of sight. He's old and they were heavy. Love that dude.
