Sam was ready to take them off immediately, it was Twinks who said, let's give it 3 hours. She knows the cameras will be on her and is playing it for all it's worth.
They have missed a trick though. They should have asked Rochelle what she would do for 30 extra seconds with her husband and then told her that if they removed the cuffs, she would lose it. Then they could have got her to wait on them and others.
As it is, they will either allow her to keep the time which she won't be grateful about or they will lose the time just before the 24 hours is up and then Rochelle will feel perfecting justified in taking time off them.
They should give her the choice, either play along with their games or forfeit her time. That would have been much better and they would still have all got camera time.
