I suspect the 17-year-old was a bit distressed becasue she didn't know much about that camera. Maybe somebody gave it to her without explaining everything. I don't think we can assume a person is a "film nut" like us just because they have a film camera in their hands. No more than assuming some snooty type knows how to use his overpriced Leica. (Not that I have anything against Leica shooters. I owned a 3F with several lenses and an M2R with two lenses.)
And some people just don't care. They just use what they have, and are not interested in their materials on a technical level. It's something I admire and wish I could do sometimes.
