Don't worry about it too much. You're gonna be working with some no-nonsense lady named Cathy who's been doing this for 30 years and she won't take any guff from anyone.

In my experience, poll working is about as dangerous as watching paint dry. Also, about as exciting.

Even when something does pop off - the Brooks Brother's Riot because the only genuinely dramatic incident I could think of in the last 30 years - it's highly localized and ultimately uneventful (from a violence perspective).
