Mezzanine Seating Etiquette

Just a quick PSA: if you're sitting in the mezzanine and you're not in the last row, PLEASE don't lean forward!! The other night I couldn't see more than half the stage because the people in front of me kept leaning forward.

I know many people may not know this, especially if it hasn't happened to them, so I just wanted to put this out there so everyone can have a pleasant theatre-going experience.
