Zonko being a student/chara's name (not that it's the most realistic slice of life comedy) is more surprising than myou-chan doing actual behind the scenes work, even if she does seem 'incompetent' to the student eyes they prolly wouldn't give that kinda job to someone super bad unless she was rich/connections or an actual job that would be considered 'easy' by JP standards (and even then i imagine that kinda stuff would be competitive for those wanting to escape a 'black company' office job XD)
