I walked into my post office today with some misc parts to send, one of which was a B5 SOPMOD stock. I had wrapped it up in blue painters tape, so it basically looked like a triangular blue object. I grabbed my bubble mailers and went up to the clerk, and it went like this:
Me: Hi, I'd like to see what it costs to mail these regular post.
Derp Clerk: What? What is this?
Me: Huh? Things I'm shipping, I want to find out the cost to ship it.
DC: What is it?
Me: What do you mean? It's parts, machine parts.
DC: Machine parts? What type of machine?
Me: What does it matter, none of these items are something I'm prohibited from sending.
DC: (walks away)
There no one else in line, and another clerk right next to me. I just shuffle over and tell him my dude asked me questions and then left. The new clerk chuckled and proceeded to quote me prices. A couple minutes later when I'm about done, Derp Clerk returns with his boss.
DC: (to new clerk) Did he just go to you when I left?
New clerk: Yea...why?
DCs boss: (to me) What is this? (Pointing to B5)
Me: Parts.
Boss: Is this a gun?
Me: No.
Boss: Ok it's not a gun?
Me: It's not a gun, it's a piece of plastic.
Boss: Ok, because you can't mail guns.
Me: It's not a gun, I'm not sure why you think it is.
They left, I checked out, and went home.
This guy really thought I took a gun, wrapped it up in blue tape, and tried to mail it off in a bubble mailer.
I know, cool story.
