"We're required to use UPS at work for overnight packages (we have a lot of them), and they're the worst."
They really are bad. On more than one occasion, when it's getting late, I've seen my UPS delivery guy drive right past my apartment building. A few hours later, I would check on line and my package would be marked as "Delivery attempted". I didn't know that driving past my apartment building without stopping is considered an attempt.
"Well, I've had a LOT of trouble with USPS, involving regular letter delivery as well as packages."
Last month I had two packages from Amazon stolen. I called the USPS and they said the delivery person put them in the hall. I told them there was a reason we had locks on our mailboxes and that I didn't consider just putting it in the hall as delivering it to me because there was an apartment number on the address and it should have been delivered to my door. If I lived in the suburbs, they wouldn't just throw it on the lawn and call it delivered (or maybe they would?) Anyway I'm out $60 because Amazon says they shipped it and the USPS says they delivered it.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
