Ya know, she's been going full bore from day one to be "the best" in her quest to be a receptionist, and I don't recall anyone else questioning it, so I assumed that in this setting receptionists were more like guild masters or branch leaders with crazy high requirements. However, it looks like that's not the case. Nunnaly's just a weirdo.
Also, anyone else amused by the dudes being made a fanservice spectacle while the girls got a "deep lesson"?
