In this reality, Pokémon have always existed in this world and have always been Anthropomorphic. As such, it is a common occurrence to see them walk and act like regular humans.
Now, back to our story.
After a long day, filled with trials and tribulations, it was time to relax. And you decided to do so by going out to eat to your favourite place: a local diner that always had clients even before the Anthropomorphic Liberalization Act.
Entering inside, you were greeted by its usual hectic atmosphere: people chatting and eating, voluptuous Pokémon waitresses serving drinks and dishes with a smile... and of course, the local oglers, who just came here for the "show"
However, one peculiar waitress caught your eye. She was a Gardevoir, thin as a lath, sitting at a table alone, eating a salad. Once you approached her, she looked up from her dish with an uneasy look in her eyes.
"U-Uh, hello? Can I help you?"
