Remember when they used to have a psychologist (Carmel) on staff who used to check on the hm's regularly? That was when BB actually messed with their heads though. They describe him as "kind" and "considerate" now. It's like he lives in the world of rainbows and unicorns.
Re Tully, she is the master of getting free stuff. She would take whatever she thought she could get away with asking for. I doubt she's paid for anything since she left the house. I think it gets offered to all of the hm's. If the were offering, she sure as hell would have taken it.
