I happened to be watching the other day when the UPS delivery guy arrived at our house and then proceeded to have a package fall off of his...skateboard? I guess it makes it easier to push the packages and then he can zip back to his truck on his skateboard. Anyway, he knocked and then waited for me to answer, acknowledging that he had indeed dropped a package and heard what sounded like something breaking. He said he would wait while I opened the package. Lucky for him it was a bunch of metal brackets. I was impressed with his honesty since he didn't know that I had been watching.
