No need to wait on line at all. Just do what people do now when they pick up their mail at the post office: Take your key over to your P.O. box, open your box, and get your mail out of it.
Yeah, I did that in college for a while when I moved constantly... but it wasn’t worth the seventy bucks a year it cost me.
Still isn’t.
Great, so now our post office with parking for 60 cars will have hundreds of people stopping in to check their mail before or after work. We'll need the cops out there to direct traffic.
