Proper packing

Fedex: 1) 20? years ago, they were inordinately proud of how few packages were late. Unfortunately, to achieve that goal, they had an unacceptable algorithm. Instead of a FIFO buffer, . . . if a package were late, it went to the BACK of the queue! Therefore, they had one package 2 days late, instead of 2 packages 1 day late. At that time, UPS had a FIFO buffer, and therefore had more late packages, but each late one was substantially less late than Fedex's late one. 2) A few years ago, I was expecting a package. Somehow, I missed the first two deliveries. Not sure HOW, since I was anxiously awaiting it. So, I took a entire day off of work for the third attempt, and spent the day sitting on my front porch. At 2:00, the online tracking changed from "out for delivery" to "failed delivery attempt"!
