My husband just remembered something from his childhood town in Pennsylvania.
If kids got an ‘A’ on their report card, and brought it to Big Boy, they’d get a free meal. He says that with four kids at the time, it was a nice, cheap treat for his family, every school-report cycle.
(He says he always got the Big Boy burger with ‘everything’ :-)
Wow - that was a good “promotion” from that restaurant!
