Yep, or I have seen staff heckling an old guy because the tip of his case wheels stuck outside of the sizing device, while some moron with a hockey bag sized duffel walks on and nobody days anything.

One flight was packed and so the host was asking everyone to turn their bag sideways in the overhead as we boarded, and while saying this over and over people still were laying them flat. I said "This must get old, it is like dealing with children." He said, "no it is worse, children listen, these adults don't."

There is also the issue that airlines have been stuffing seats tighter and tighter. So more people without an increase in overhead compartment space.

My number one gripe is why they charge for the stuff people don’t want (under plane) but offer what people do want for free (in the bins).

I know it’s a pain in some flights to wait for the cargo unloading but the other side of getting on a plane and doing transfers with nothing but a small handbag is so nice.

One carry on, one personal item. A personal item can be a backpack. I don't remember the last time I checked a bag.

I once saw someone had a MASSIVE backpack. Like; triple strap hip, belly, and chest strap backpack; probably 15kg (33lb) or something. I think it just barely technically was allowed when they were weighed. They were struggling to carry it.

Then I realised they were a small group, and all sitting on the same row, and all 4 of them had one of these backpacks. They took up two entire overhead carriages by themselves. Other people had to put their luggage and belongings in random places around the plane where there was space. Everyone was in a flurry to try and stay on schedule, it held up the whole plane lol
