When I was a kid, supermarkets gave out “green stamps.”
People would paste the green stamps into little booklets.
The green stamps companies (the one that comes to mind is “S & H”) published catalogues featuring all the goodies you could get by redeeming the appropriate number of completed stamp books.
I remember asking my mother if we could “go to the redemption place.”
She replied, “Sounds like a church.”
Whenever I see a sign that says “Validation,” I think of that incident. And I make a little mental joke about its possible alternate meaning…
…A thought that obviously also occurred to this clever filmmaker.
