Hmmm - years ago I was travelling slave LHR-SIN with SQ
My checked luggage was right on the limit and I was carrying about 20 kg of books in "hand" luggage - the check-in clerk asked - "any hand luggage sir?"
I cheerfully grinned - picked up the bag one handed and held it at arms length - "fine she said" - I strode off to collapse in a grey sweat behind the nearest concrete pillar - I couldn't use the arm for weeks.................................
