Delievery guys bored or just dumb?

The FedEx guy just started this. The UPS guy has been doing this since day 1, but he will put the box under the mat in its normal position in the middle of the door. I'll give the FedEx guy the benefit of the doubt and say he saw the wet spot there and figured it'd be best to leave it on a drier section of entrance-way. For reference, that's an 18x14x12 box under the mat. So it's not this little subtle bump.
I hope they are just bored and have a sense of humor, because it's probably something I would do if I had their job.
