Draw a Business Process Model for the process of booking a cinema ticket from the ticket counter:

The customer approaches the ticket counter next to the entrance. The staff shows the customer the movie listings and the showtimes. The customer selects the movie and checks if the time is convenient. If not, then the customer selects another time. If no suitable time is found, then the customer chooses another movie. Then, the customer selects available seats. If found, the staff confirms the booking.
