I don't know if this is fraternity-wide or just Delta Iota, but I know our officers were required to arrive first and depart last for all social events (probably a pretty standard risk management procedure). It was kind of an understood unspoken that they would be there to make sure that nothing got too out of hand, but for the most part nobody needed babysitting or anything.
Also, my big was an officer, and she once got a slap on the wrist for getting too riled up during the UGA/SC game!
Since she was supposed to be an example, I suppose some people felt that a warning was validated.
