Here at the Demon Slayer Zesty McDonald’s worked Tengen Uzui (the store manager) working at the cashier, Mitsuri Kanroji (a employee) working with the McFlurries, Kyojuro Rengoku (a customer) sitting at one of the tables eating 20 Happy Meals and 40 Zesty Meals and a Grimace Shake

Tengen: Wow I wish my three absolutely stunning wives were here

Mitsuri: thinking about Obanai

Rengoku: UMAI!
