I never heard of this type of store. I just googled it, and found there's one that opened in my town over a year ago. Tired of being one of Amazon's highest sources of income, I'm going to check out that store soon.
I honestly thought McDonalds has been doing this for years. They've already proven in court that their shakes contain zero dairy products (which is why they have to call them 'shakes' instead of 'milkshakes') and are based on a synthetic plastic-like product.
Last year, I bought a house in Little Rock that was built in the 1950s. That's from the last century! It astounded me to think of all the people, now gone, who have lived in that house before me.
