I've flown a lot and will agree with this one!
Some people are such idiots when it comes to boarding and stowing. Then there's that special breed of dick head who has to get by me into their seat and then three minutes later has to get back up and go to the overhead luggage compartment to get something. Then they sit once again and then...luggage compartment for something else. On the third time I usually grab them by the scruff of the neck and lock them in one of the bathrooms for the duration of the flight.
Ok...not really.
Or do I? 😉
