I feel for the cabin crew.They're trying to look professional and friendly, obligatory smiles every 10 seconds whilst swinging half their body weight over their heads and bouncing them into the bins. All whilst buttoned into a tight outfit, balancing on heels and keeping theirs hats straight.
Admittedly the above is on ME and Asian carriers. Many euro crews seem to push straight back straight back with 'If you can't find space it's going in the hold' or 'Then it will have to go under the seat' both options leaving the pax cheesed off.
