For example, delivery services routinely leave packages at my garage rather than my front door, because it saves them 15 seconds of walking. This is less convenient for me but more convenient for them.
But that's not all! Once they put a package low to the ground and not out of the way, so that when I went to drive somewhere, I backed over it.
I once saw a delivery guy deliver to a neighbor. He dropped the package at their garage door, knocked on the garage door, and left. I assume they are required to knock but it doesn't say where.
And of course because they never knock or ring my doorbell, the only way I know a package has been delivered is if I sign up for electronic notifications, or I discover it on my way out.
In other instances, I've had packages simply delivered to the wrong house, I guess because numbers are hard. Once I had a package delivered to the wrong city.
Usually it works well enough, but there's plenty of room for improvement for me.
