In my locality, both the TOSA and the TIMES were sold by the Marcus chain as sub-run houses, but the buyers of the small vintage cinemas couldn't make a go of it, so they asked Marcus to waive their sale restrictions which were apparently within Wis. law. There were a number of articles in the papers about 'big old baddy' Marcus restraining trade in these under 500-seat cinemas not too close to any of Marcus' multiplexes.
After standing firm for over a year, and enduring adverse public comment about themselves, Marcus relented and waived the terms. Both cinemas are just making it now, about 5 years later. Maybe if nothing else works, you can shame them into relaxing deed restrictions. Best Wishes, Jim
