I worked at the local A&W as a teenager. Dad loved it when I worked the lat shift because I alsways came home with leftover, Papaburgers, Mamaburgers and Teenburgers. Their tacos came frozen and were dropped in the deep fat fryers . . . they were delicious!
I remember the small frosted mugs filled with root beer for kids.
Ahhh.... meat paste tacos, so bad they’re good. Two for 99 cents at BK. Still get them on occasion.
