FedEx and UPS nixed their on-time delivery guarantees once COVID appeared.
I had a package lost by UPS for a week with no tracking update. A week later it's out for delivery again, gets to my house, and no delivery attempt is made. I get on my mountain bike and chase after the UPS truck.
Turns out it was delivered somewhere and some idiot had written "Does not live here" on the shipping label so the UPS guy just flagged it as having an incorrect address (despite the address being correct) without making an attempt to deliver it.
At the same time, my packages were sitting at the local FedEx depot getting "local weather exceptions" several consecutive days when it was 60 F, windless, and cloudless.
