I recently went to the wedding of FI's college friend. They had four attendants on each side. There was a friend of the bride's that clearly didn't "make the cut" and was very clearly unhappy about it. No, I don't mean she was a sourpuss guest who just complained about everything or got drunk and ruined the first dance or something. No. She wasn't good enough to be a bridesmaid, but she was good enough to be the guest book attendant, apparently. She sat at the table the entire time, glaring at everyone and snapping "Sign the guest book" every time someone walked in the door. The MOH tried to talk to her, because this was upsetting the bride. She just threw up her hands and walked away from the table. No one saw her again for the rest of the night. Maybe that was immature of her to throw a hissy fit, but seriously, people, your guests are not helpless baby dolphins. They can see a guest book and pen and know what to do with it. Don't give people crap jobs as a consolation prize.
