I am asking this question again as the first answer was a little garbled please help!

At the Main Street Theater the cashier located in a box office at the entrance receives cash from customers and operates a machine that ejects serially
numbered tickets. To gain admission to the theater a customer hands the ticket to a door attendant stationed some 50 feet from the box office at the entrance
to the theater lobby. The attendant tears the ticket in half opens the door for the customer and returns the stub to the customer. The other half of the
ticket is dropped by the door attendant into a locked box.
