What's odd is if it clearly is such an unpopular soup there, why does the store carry so much of it??
Mind you, I know that once upon a time, cream of mushroom soup was in most-every recipe in the 1950s. And I can see them selling a lot around Thanksgiving for that spinach-fried onion crisp casserole . But not being Thanksgiving (let alone Thanksgiving in the '50s...) and clearly it isn't selling now, that's what's so weird about them having SOOO much of it.
It was really funny -- empty shelf after empty shelf after empty shelf, except for all that cream of mushroom soup. People really didn't want cream of mushroom soup. Even in a hoarding panic. I mean, seriously people cleaned out ALL the cans of soup. All of it. Except the cream of mushroom soup.
I wrote about this on social media, and people were trying to come up with explanations and not all the things people really do use cream of mushroom soup for. What I tried explain was that -- whatever the reason it's the only soup still there and however many reasons there are to use it -- the only point is that it's odd. Odd that cream of mushroom soup is the only one left on the shelves, and odd that the store still stocks a soup that clearly isn't being bought like all others. (Shelf space is tremendously valuable and competitive. If a product doesn't sell enough, it's replaced.) So, that's the only point -- that it's odd. And really noticeable. And funny.
This photo doesn't even do it justice, since you can't see how far the looooong rows of empty shelves go -- empty except for the cans of cream of mushroom soup. And yes, all those cans are only cream of mushroom.
