I will almost never pick UPS any more. I just refinanced my mortgage and had a significant sum coming back. The escrow company sent the check UPS express. Some 6 days later, I was wondering how long it was going to take to get my money (I was not aware they sent it out 2 day express, 6 days previously). We happened to order pizza delivery that night, and when I opened the door to get the pizza, I noticed a UPS envelope on the porch. Yup, there it was, a bit soggy, while the porch kept it from being directly rained on, the damp certainly was in the cardboard of the express packet. UPS just casually tossed it on the porch and took off. We do not normally use the front door for anything - we always come in via the garage. Had we not ordered in that night, it could have been there another week. Luckily as a flat envelope it wasn't visible from the street, not that it would be easy for someone else to cash a check made out to me.
I've had similar experiences with almost every service.
The one and only time I had mail stolen, the postman delivered a package of priority boxes I ordered and leaned them up against my front door which makes them about as visible from the street as is possible to do. Then he "helpfully" left the rest of my mail on the doormat where it was all stolen from, despite the fact that I have a secure locking mailbox on the street for precisely this reason.

Shortly before Christmas FedEx delivered a box containing gifts I had ordered, I was at work downtown but saw on my security camera that they had set the package right on the edge of my porch, again in plain view from the street, right in the middle of the one patch that was already damp and just minutes before a torrential downpour was forecast. There was a nice dry corner just a few feet away. Even if I had left work right then and caught a bus home it would have taken me over an hour to get there.

Thankfully I was eventually able to reach my mom and she drove over and retrieved the already soaked box, took it home and set it by the heat vent to dry out. If it sat there any longer it would have been completely destroyed.
Multiple times I had UPS deliver packages to my house number on the next street over, I would call them and they would insist it was delivered and cite the driver signing off as "proof" and ask me to look around my house for other spots it might have been left.

This finally improved after I called to complain multiple times and told them the neighbor had just dropped by with my expensive package *yet again* and they said they would flag my address.
DHL delivered a computer to my next door neighbor. I was home and eagerly watching the delivery progress and then got a notification that it had been delivered, checked the porch to make sure it wasn't one of those silent ninja deliveries Amazon is known for but nope, not there. Finally called them and they sent a picture of the delivered package which I just happened to recognize as my neighbor's porch. I went over there and they weren't home so I just grabbed my package.
This all strikes me as extreme incompetence but what can you do? I can't think of a carrier that has not made one of these bone-headed errors.
