So over a hundred people have to line up for the one or two washrooms at the back? That would drive me batty if I was sitting near the back. And not to mention a huge inconvenience and safety concern to the cabin crew who are working (or trying to work) in the economy section. I think it’s unreasonable on a narrow body aircraft to allow only 12 people to use the forward washroom and the rest have to pee their pants waiting for the remaining washroom.
