I always assess the situation. Sometimes I will politely ask someone to tone it down, sometimes I will sit on my legs to raise myself as high as I can so that I'm blocking their view, if they're behind me. I've ignored it, moved, and advised management but never got any free tickets.
How'd you do that, cyn?
As for rubber bands, I'm no longer allowed to carry 'em. They've been declared lethal weapons in my hands.
