Ahh hand luggage, now that really grinds my gears. On a flight today from THR, there were so many people with bags that they could barely lift onto the aircraft. Leaving a bag in the middle of the aisle will not make me put it in the overhead locker!!! I just tell the passengers that if they can't lift it into the locker, then it will have to go into the hold. One lady complained that carrying her case had given her a bad shoulder! Obviously, if it is a handbag or duty free bag, I will do it but rollers and hold alls are an absolute no no. I also care for my own safety!
