Be careful what you wish for...
Many years ago, I flew Swiss business class on a European hop. Their version of a business class bus was one bus, separated with a tensa barrier half way down. I was directed to the front half of the bus. The rest of the plane was directed to (and crammed into) the back half of the bus.
Turns out I was the only person in business class on that flight. I certainly felt more than a few eyes on me on that bus ride.
