Not to sound flippant or dismissive of the death of a human being, but how is this news?
A) It's a Waffle House.
B) There was a murder.
A always implies B. In fact, all jokes aside, I don't think there's a single Waffle House in the US that hasn't seen at least one murder.
That said, the macabre humor is kinda funny, anyway. Or maybe it's just that I have to laugh so I don't scream at yet another mass shooting in the US.
