For me, it may be that the toilet paper roll needs to have the open end away from the wall. I don’t want to reach under the roll to take a piece! That’s ludicrous!
That or my recent addiction to correcting people when they use “less” when they should use “fewer”
I flew on an a380 recently. They actually used zoned boarding! The number of people who didn’t seem to get that they wouldn’t be allowed to board till their zone came up was amusing.
It saved a huge amount of time.
My planes had groups, but I don’t think they were grouped by seat.
