The staff treat the customers as masters and mistresses in a private home rather than merely as café customers.

In other stores, the outifts and even the setting itself change. In school-themed cafes, for example, the term employed to refer to the customers is sempai instead of master or mistress. Inside, regular tables are replaced by school desks and even the menu is served in trays reminiscent of the ones used in Japanese schools.
