Yes, I can understand that tall people often find the legroom tight and to feel more comfortable stretch their feet in the aircraft aisle.
I can also see your point when we are doing the service back to front, however it is usually when we are doing the service from the front of the cabin (meaning people can see the crew member!) . Somehow, they just ignore the fact we are wheeling the trolley and we still get the "you should be more careful" and the evil eye from a few pax...
