First I'll give you a brief history of my UPS experience that no one will care about, then I'll get onto my question. I worked at UPS as an unloader years ago before joining the Air Force. After retiring from the AF finding a job was difficult. UPS was hiring (2 years ago) off the streat drivers so I applied. I drove the truck very well, managed the back of the truck well, am physically fit so the physical demands of the job didn't bother me, but I had one problem that I have struggled with my entire life that I couldn't overcome. Geographic Dyslexia. I don't think that's a real term, but it's a term I'ver heard recently from a fellow sufferer. Where I live (Utah) we use the grid system. On a map it makes absolute perfect sense, but when I'm driving and thinking about my next stop, literally nearly every single instinct I had was wrong when it came to knowing which way to go next. When I went the correct way it was just luck. So I lasted about 15 working days driving. I quit because I knew I would be let go at the end of my 30 days. It all worked out in the end so no tears for me please. So, I have the utmost respect for UPS (and FedEx) drivers, and I defend them anytime someone complains about a delivery or driver, etc. Which brings me to my question. In my "extensive" experience with UPS, I never saw this happen. My friend had this all on video. The driver drops off a package. Then a short time later he returns to retrieve the same package. My friend got the Amazon email saying package was delivered. When he got home of course there was no package. The same package was then delivered the following day. So what gives?
