So here's what I am thinking: it's either one of two things: a Trekkie down on his luck and so far removed from reality be holds up a convenience store with a Bat'leth to get money for more collectibles... or... a thief who stole the Bat'leth, has no idea what it is, but thinks it's a "bad ass martial arts weapon of some kind" and hopes the clerks will think the same.
I am betting on the latter.
