Odd and annoying: I went by the post office last night after work to pick up some stamps (those wedding thank-yous are finally just about done and now we have to start our Christmas cards). I had a $20 bill and a single all ready to get 3 books stamps ($6.80 each). I put the bill in, but nothing happened. And then I saw the electronic message scrolling across the stamp machine: “Please use only coins.” What? Who was going to buy a $7 book of stamps with coins? The other stamp machine, which only serves up a stamp at a time, displayed the same message.

I don’t know whether it was some weird double-malfunction or if some weird security precaution I’m unaware of.
