Trans-pacific experience
The only thing that really ticks me off is when it's meal time and the person in front of me hasn't put their seat straight up and they are just going for the food w/ the extra room. not only do I have to deal with their seat as an overhang over me, but it's down right impossible if you're petite (I can't eat leaning back and keep my feet on the floor at the same time).
This was easily corrected on a flight on Air Canada ICH-YVR. The flight attendant gave me my food and the person in front of me who still hadn't put their seat up was going at it with their food. I informed the FA who kindly went up to that gentleman, told him he had to put his seat up and promptly pressed the button and pushed it up for him when he refused to do it in a timely manner.
