I pretty much always go to the movies alone, and that's by choice. In fact, I don't like it when there are more than about 3-5 other people in the audience total. Just shut up, sit down, and let me watch the movie already.

I go often enough that the people in the box office know me and that I'm only going to get one ticket. And I really don't care what random people I'll never see again after we watch the same movie think of me.
