Q. When walking into or out of a row of occupied seats, is it more appropriate
to face toward the seated people or away from them?
It is appropriate to face toward the seated people, also, it makes it more convenient to say “thank you” as you pass by. The correct answer is that you face the stage or front of the house. This gives the performers the respect they deserve, it also leaves you free to use your hands on the back of the seat in front of you if you need to catch yourself.
