I don't get paranoid about these guys.

Just had a UPS COD.
It was getting late so I called UPS and it turned out that the dumb arse shipper had left off my STREET in the address.

So I definately was NOT expecting him to show up.

But he did, and being a friendly guy I asked about it; they had looked up my street (Should I be surprised? I mean that's not rocket science), and I thanked him.

Then he mentioned the $ amount for the COD, and said ( with a quick shake ) "Meds? That's expensive!"
I said (being older than he) "Just don't get old, ha ha" and we exchanged a few more banalities - and told each other to have a nice day I would say he is a friendly guy.

What did he really think? What does he know? Will the black/silent helicopters be hovering overhead?

I don't worry about it. They're doing their job, and I'm sure many know what's what. And hey, the shipping companies certainly profit from it.
