Pirates, like the one working at the cash register, often would mutiny if they felt they were being mistreated by their captain; you can say that there's a broad consensus a a mutiny is coming by saying it's figuratively "in the air". But, in this coffee shop, the smell of Viennese dark roast is literally in the air: this contrast of figurative serious mutiny threat and literally coffee both being in the air is funny.
