“Fake money for drug dealers” is just a general crypto joke from a meme I saw here on lemmy. It just so happens that the flavor of fake money that you fell in love with actually is for drug dealers.
You’ve got me curious now though. It’s apparently important to you to keep the details of your grocery purchase completely private and that’s totally fine if it makes you happy. I don’t need to understand it to accept it. What I want to know is how far do you go to protect that privacy? Do you give Instacart your neighbor’s address? Do you use a fake name?
