I’ll go first: r/kitty. One of the hundred grillion cat subs back on Reddit, the culture in this one was you posted a cat picture, and the only word allowed in the title or in any comments or replies was “Kitty.”
Someone is using that subreddit for covert communications, I just know it. Either on the level of “if u/PM_me_your_nostrils posts an orange cat, we attack at dawn!” or there’s some steganography going on with the pictures, but that subreddit was too stupid to be as active as it was.
Restaurants often do get first-pick, but it’s probably just because the producers or distributors can make more money selling to them rather than the grocery store. I.e. just another feature of capitalism. This happens with a lot of things, such as home builders and furniture makers getting first-pick on lumber. Now that I think back to when I used to work in fabrication, steel as well.
