It depends where you live. Out here in nowheresville, our postal carriers are friends and neighbors, and we get great service. All the delivery drivers are very nice, USPS, FedEx, UPS. We get more broken stuff through UPS, though.
I live in a rural area and my postman cursed me one day when I asked him a question.
My UPS and FedEx drivers are phenomenal!
In fact, I get irritated when I buy something online and find out they are shipping it via USPS.
“We get more broken stuff through UPS, though.”
If you’ve ever seen how UPS loads a truck, you’ll NEVER ship anything of value with them again.
DHL used rolling containers for all of it’s freight. They rarely damaged anything. Those days are gone.
