First of all, I have no idea why pkg needs signature. It's already paid for, it's not dangerous and it should fit just fine into mail box.
Secondly, because I had been given no warning that it would need to be signed for, I missed first attempt at delivery so the driver leaves a note specifying that they will return after 5pm next day. Made inconvenient arrangements to be available and waited until 8pm before checking online and finding that they returned 3 hours earlier that day at 1:45 and the note they left this time informing me of their 'Final Attempt' at delivery did NOT specify a time to be available for their last attempt the following day.
This is absolutely unacceptable. If I cannot be here tomorrow to receive and sign for this totally inert/benign package, then it will be returned to Manufacturer losing money for both them and I.
Is this how UPS strives to do business?
