I used to live in a condo/apartment complex with an A and B side. My unit number was one of the B's with a matching A. I had ordered motorcycle gear, and was watching the fed-ex site the day it was to be delivered. When it popped up as delivered, but we didn't have it, my ex went ballistic on Fed-Ex, who also said 'not their problem.' I decided (luckily) to walk across the street, & sure enough, it was delivered to the corresponding 'A' unit, and the occupant was honest & handed it over. My ex decided to go ballistic a 2nd time on Fed-Ex, who still didn't care, because we received our package.
