Having to put on shows with occupancy limitations from the Governor is difficult.  We have a maximum limit on the total number of people in the building and are required to sell tickets in advance.  Tickets have been sold in time slots by estimating how many people will be leaving during the previous hour.  There may be an occasion that more people will have left the show than the tickets we have sold.  At that point, we could sell walk-up tickets but have no way of knowing this in advance.
