WFISD cafeteria workers honored for School Lunch Hero Day Share on Facebook Share on LinkedIn WICHITA FALLS, Texas (TNN) - Throughout the cafeteria line at McNiel Middle School, you can hear Crystal Brock’s catchphrase ring out as she gives a “thank you, baby,” to each student coming through. “Sometimes the kids come in and they just can’t wait to tell you how their day has gone,” she said. While it may have been School Lunch Hero Day across the Wichita Falls ISD, for Brock it was a typical day doing what she and her family have loved doing for generations.
