"When I was a kid we still practiced "fish Fridays" ( being a Cafeteria Catholic, I just do it on Good Friday now laugh ). My mom would often get me to participate by taking me to McDs for the Filet-O-Fish."
Yep, that was SOP at my school in the 1970s-80s. Fish sandwiches at lunch. And, believe it or not, the fish sandwiches we had were incredibly good, even better than MickyD's.
