You forget the boredom factor. Adele was happy to do the housework because it was something to do. You have to put yourself in the position of the housemates, those on the rich side last week were fairly envious of the poor side because at least they had something to keep them occupied. Sandy moaned that now they had a laundry service that was "one more thing they've taken from us." Imagine being confined in a couple of rooms with nothing to read, no tv, no computer games or any other source of entertainment with 11 complete strangers, it's hell on earth. Adele waiting on them hand and foot, at least she had something to do, selfish cow.
