I'm always in an aisle seat and if you don't get up at the ding then the space beside your seat will be instantly filled by someone who does. Seatbelt light off, stand up, retrieve bag from overhead, place it on my seat and wait until the queue moves forward. Let people in aisles before you go ahead if they are standing and ready, move into any empty space that is created, stare with resignation at the dummies who stand there and fiddle with their bags, put on their coats or otherwise block passage.
