Michigan seniors have a good reason to get an early start Friday morning. Big Boy restaurants across the state are celebrating National Senior Citizens Day on August 21 with a free breakfast buffet for qualifying older customers. There is a catch, however: the promotion isn’t an unlimited free-for-all, and arriving late could mean missing it entirely. Customers must be at least 62, purchase a cup of coffee, and be among the first 100 qualifying guests at their Big Boy location. Here is what seniors should know about the Big Boy free senior breakfast before heading out Friday morning.
