Even with all the effort put into getting the counts right on the customers grid, it still didn't work right. The root of the problem is the join to CurrentLease, which can result in multiple rows for the same customer. I can revisit this in the future to put some clever solution back in, but in the meantime, it was easiest just to add fields to the customers table, and simply update it whenever the customer lease situation changes. I don't like it... but it just made life much simpler.
