While I am in no way affiliated with the Buckeye Regional, if you had issues such as what I am reading here with a volunteer, I highly suggest you contact the volunteer coordinator for the event. Contact information for Buckeye is on
http://www.oai.org/firstbuckeye/volunteers.html
Conduct such as what I've seen described is no way for any volunteer to act, especially in a key position.
