Do some of the seats need minor changes insisted/suggested by the club.
There are plenty of single seats, sometimes with two on a row, if a few seats were moved one place you'd have two seats together which would be easier to sell than a single seat. In SE corner there is single seat, two occupied then single seat again? Do the club put any controls in place for not leaving empty seats, even the Civic theatre website does that so you don't leave a single seat on its own which is harder to sell.
