The idiots that bring massive suitcases onto the plane as their carry-on. And then still haul on a personal item as big as the "allowed" carry-on size.
"The overhead cargo space on this flight is full. After letting six passengers board. Everyone else please check your carry-on bag at the gate."
The worst part of flying, boarding and getting off the plane after arrival, is made worse by people straining to lift their massive bag in and out of the space not designed to hold a large suitcase.
These people should be shunned by all. They deserve whatever embarrassment, inconvenience, and cancel culture comes their way.
