I had a large printing order delivered to a school that was not delivered. UPS excuse was that the school parking lot was empty and that the school was closed.
My wife is a teacher at the school and was at work all day and she had a view of the front parking lot and nobody came by.
An automated message said they came by at 9:30 am and the terminal said they thought the school was closed so they did not stop. Also their phone system was terrible in that the operator was not helpful and the connection was bad.
