I was on the other end of that. Last christmas my wife went to visit her folks in another province. They had sent us a christmas pkg via purkolator (the instructions were to leave it on our porch, which the courier ok'd at the sending end) Of course they didnt leave it on the porch, I had to go and pick it up and there was only 1 working day left, and they were across town so I just got there 5mins before they closed.

I could tell they were ticked off when I came in, as they were getting ready to leave. One of them told the other staff to lock the door after me. So when I asked for the package and gave them the delivery slip they left at the door - and showed my id with the same address. They said the package was not addressed to me (it was apparently addressed to my wife) and would not release it.

when I asked if they could double check if my name is on the package
one of them did a cursory peek around the corner and said no. (I dont even think she looked) As my wife was away for 2 weeks and only she could pick it up, the package would be sent back after 7 days as it was not picked up.

So as I left i thanked them for nothing.
to which they shouted something behind me.

later I phoned purkolater and they said they could extend the pickup time. When my wife called to complain, as her folks had paid extra for deliver before the xmas weekend about the only thing they would do is ask the staff to call me and apologize.
(which one of them did and left a msg although it wasnt particularly heartfelt -)

imagine my irritation when my wife finally picked up the package 2 weeks later
and it had her name and my name right next to it.

and all for a bunch of (now stale) christmas cookies.
