Scary, wide-eyed, woman in a towel stampeding through the festival

After she took a shower she found out she needed to use a toilet too. She picked the small board up and there was a spider! Huge and drooling after her. Yum. The spider wanted to have a little snack. Her bladder need was in red so she ran, scared to almost death, and found a safe place to wee. Nothing special. Don't tell me you have never experienced this IRL as well :D
