Going to the post office is not that complicated. You only have a few different options of things you can do there. You can send a letter, pick up some mail or buy some stamps. You would think that most people probably know what they're going there before they even get to the post office. Yet people still get up to the window and stand there staring at the post office clerk wondering what to do, while the line gets longer and longer and people get angrier and angrier...including the post office workers.
