Well, I do get what OP is trying to say. On a recent flight the last two pax to board the flight (Basic Economy) were assigned seats in MCE. One of them happened to be a quite large person (required two seatbelt extensions) and happened to be seated next to me. While unfortunate, it basically made it impossible for me to open my laptop and do a bit of work. I did not have an enjoyable flight. And yes, I understand that this could happen anyway, but I select MCE to at least be able to sit and open my laptop (and even try to minimize that).
