Popeyes is all sold out of its ridiculously popular chicken sandwiches. So they just tweeted a new plan: Bring Your Own Bun. Just go to a store, order their three-piece chicken tenders, then slap them on your own bun. And boom, you're eating a chicken sandwich at Popeyes . . . it just won't have the mayo, or pickles, or the right flavor. They posted a video, and the whole thing is tongue-in-cheek. Fans of the real sandwich are mostly just annoyed though.
