Movie Theatre Seating Etiquette (with diagram)

[diamonddawg]

I would like to see a seating diagram to explain to the weenies who come into a nearly empty theater, just as the movie is starting, and sit DIRECTLY right in front of us that their etiquette is poor.
With said diagram, I can xerox it, tape it to a piece of wood, and hit them on the head with it next time it happens.
