I’d also say sign fatigue (plus general fatigue) is a thing. When you go to an airport security line there’s like these giant signboards stood up like the 200 Commandments, each with a mix of pictures and walls of text of for things you’re not allowed to bring on a plane. Or some things you can check and not carry on or you can carry on and not check. And you’re also expected to know all of that while you are in transit, stressed, and maybe also sleep deprived.

Too many signs to properly pay attention to them all.
