That's something you have to deal with in both adult and non-adult films, but I think the difference in adult filmmaking is that generally people don't communicate to you why you're waiting. There's no call sheet that tells you, "Hey, we're doing this shot and this shot and at noon we're having lunch." It's definitely more guerrilla-style, even when it's a feature film. I generally try and bring a notebook with me and write, or really sit and meditate.
