A reminder of behavior in the theater.

Some rules of theatrical etiquette:
* I think everyone knows that the theater begins with a coat rack. So, the gentleman must help his lady take off her coat (fur coat, jacket), and then undress himself. The man should keep the numbers.
* A man must enter the auditorium first.
* You need to take seats in the hall no later than the third call.
* If you suddenly find that your seats are taken, there is no need to panic and create a scandal. Show these people your tickets and ask them to change seats.
