Oh no...the infamous Karen... she will make her appearance in the coffee shop, and if you know Karens...they want full satisfaction or they'll call the manager. If you're unaware of what a Karen is, it is basically slang for a person who believes they have more privilege than others and will continue to  demand until they get their way, and in most cases that doesn't happen.

(This role may come in the future as a form of a joke, for now it's unsure.)

Note: This character won't say these exact lines in the episode, this is my way of seeing how your voice would sound for this character.
