Once upon a time, I was an Admissions Office volunteer and my "job" was to represent TCU at local college fairs when the Admissions Office staff couldn't (or wouldn't).
The brochures and handouts they sent for me to pass out to prospective students (and their parents) were full of the "lose/loose", "there/their", and "you/you're" type of errors, along with other gross typos. Specific data was inconsistent (e.g. student-teacher ratio)--within a document and between documents.
Year 1: After my first fair, I sent them a note suggesting they proofread the material better.
Year 2: After my first fair, I sent them a complete set of the material with errors and corrections highlighted in the brightest red ink I could find.
Year 2: After my last fair, I sent them a resignation letter.
