Can’t See a Thing
Do you know why you’re not allowed to pack scissors in your carry-on bag? Because there have been far too many instances of people cutting off the hair of passengers sitting in from of them. That wouldn’t be the case if you didn’t block their TV screen with your long, gross hair, you witch!
Actually, we don’t even know if that’s true or not, but it sounds reasonable. Do you remember that bald guy who was shaving his head midflight? Maybe we were too harsh on him. We’d much rather sit behind a guy shaving his head than behind a woman whose hair is blocking our only source of mid-flight entertainment.
