I remember going to the old LA Dodger stadium with my father, when, guessing mid sixties. We didn't buy food, I don't think. Maybe a coke, but no memory of that. I remember noisy people around us, when I wanted to watch the game.
Later in life, I had a co-worker who was nutso about dodger dogs. That was one of her milder obsessions, as she got onto some wrestling goofball stuff, don't get me started.
I tried to avoid having lunch in the office, thus good walks, etc. There are many reasons behind exercise.
Not that I dislike her, we have stayed friends.
