Sure. I was referring to the condition of some of those packages when they finally reach their destination.
I got a piece of mail from the USPS which happened to be half of the outer page of a several page brochure. Surprisingly, the stamp made the trip, cancelled of course. They made sure they didn't lose that. The USPS enclosed it in a plastic bag which had an apology printed on it "in case the condition in which I received the mail caused any inconvenience".
USPS and UPS are worlds apart.
REM: I spoke of FedEX and UPS ;-)
