Following your instructions
We have to admit the delivery guy/gal had an elite sense of humor to pull something like this. Well, technically they were following the exact instructions, and that too in the most creative and out of the box kinda way.

As much as we admire the driver for cooperating, the question arises about what was the owner of the package thinking while ordering? Did they order something small to fit under the mat and then maybe tap a couple of extra zeros on the shop page as well, to have received an order so big?
