Owners of the Golden Ox Diner on Wilson Road weren't looking forward to another restaurant relocation job. The last one started two years ago and still isn't finished. But their landlord at the former Kmart shopping center has asked them to move out by Jan. 15, and offered to make it worth their while, more than four months ahead of their lease expiration date. "Customers are in an uproar," said Kathy Exarchoulakos, who owns the restaurant together with her husband, Ted. They and neighboring shop owners are caught between digging in at a retail center in decline or packing up to make room for one of the country's largest companies.
