How about this one? I just went to the office at my apartment complex and found out that the UPS guy delivered five iPhones this morning - but not mine. Apparently there were still a bunch on the truck but he didn't have time to find them, so he's just coming back in an hour or two... despite the fact that my delivery says "by 3:00."
Good drivers should know what packages are in the truck and plan their route accordingly. but they also are dependent on good sorters filling the trucks correctly. Had things been done correctly he should have been able to deliver them all in one go instead of losing loads of time on having to go back a second time.
