I've always been impressed by both FedEx and UPS drivers.
When I worked at a travel agency in the late 1990s, our regular UPS guy had been a delivery driver for more than 20 years.
And our regular FedEx guy always wore shorts, even when the temperatures were near or below zero!
And, both were always so upbeat and friendly.
Now, I have little contact with them, because they merely drop something at my front door, ring the bell and then are gone.
