Okay

Did you know the Post Office has an APC? That's an Automated Postal Center. If you need to send a package you can do so easily with the APC. It weighs it, gives you delivery options and prints the postage so you can send a package without ever seeing a clerk. It even takes ATM cards. If you only need stamps- individually or in a book- you can also get those without seeing a clerk from a stamp vending machine. I mean it doesn't make sense to wait in a long, slow moving line if all you need is 3 stamps, maybe a book of stamps, or to send a package and you haven't any questions about it. So you go to the APC, or the stamp vending machine. What wonderful machines. They even save on labor costs, so the more you use them, the more likely you are to take someone's job.

... I don't know yet... No, I don't know... You need to tell her you won't be there... Yeah... Okay... Okay... That should be fine... Oh you're going to pick it up... Okay... That'll be fine... Oh while I have you, Mike Andrews died... Heart attack... Probably... No... I know... I know... Hold on a minute...

This machine won't be available for a while. You'll have to get stamps inside.
