That call was one of several. This is FedEx, we need the commercial invoice and proof of payment. The invoice is in the pouch per your instructions when we printed the labels. They are not there. Yes they are, I put them there myself and carefully sorted the 9 labels into the correct groups of 3 for each pouch.
They can't find them.
Not my problem and no proof of payment is needed for a gift. Would you like me to generate you a receipt for zero and send it over? No
Okay, tell them to look in the clear plastic pouch with the zipper on it for that purpose.
They can't find them and they say they aren't there.
Fine, tell them to throw the parts away and I said they are too stupid to breathe.
Then they did it again with almost the same conversation.
When the parts finally did arrive, the owner verified that the pouches were intact and all the proper documents were in place. They are just fucking stupid.
