What If? Every Salesman or Cashier or or Trader or Merchant(whatever)was replaced by the Potion-Seller whenever a transaction is involved?

[CarlManvers2019]

Just replace "potions" with things like books, drugs, guns, alcohol, coffee and so on

And yes, the seller DOES constantly insult and belittle the customer and say they're not worthy or capable of using said product

This goes on for an entire year everywhere
