I don't agree that you should have to get up and get something. The call button is there for that very reason. Most of my travelling is long hall business class. If I'm in the middle of watching a movie, I'm not getting up for anyone. I get worse than that. If there is no response to my call in about 5 mins, I turn off the call and push it again (can hear the "ding" in the galley). I repeat this until someone comes. Maybe I am just lazy and impatient ....
