Depends, are the auditioners filling out forms with their basic info? (Age, vocal range, gender, etc?) If so, then I'd think only the management team would need a record. Time spent, number of rooms needed, which staffers were present, and any major snafus/meltdowns/security issues.
I'm of two minds about documenting rudeness in the lobby. Part of me thinks that this is better done via soft-communication to the casting team. However, I did have an occasion where the only record of behavioral problems with an actress were in my reports until the day she was found with her hand in the box office drawer.
