Usually, whomever is in charge is caught off guard to see a woman official walk in. You won't believe the faces I get when I ask the coach where the officials get changed. But I usually get there earlier than my partner anyway. If that's not the case, then we take turns and the pregame in there too.
But there's always the couple guys who try the old "Shall WE get changed" bit. But I guess keeping the men in line is a part of my job! Hooligans
