The writers are really doing a job on Gail these days, my mum just asked if she'd been drinking!
Carla can't have gambled that much, surely? Serious plot hole. As if a bank would allow a 30k overdraft. Carla was only transferring 2k into her personal account the other week. I don't think she'd ever start gambling straight out of her business account and I don't believe she could have kept transferring it and not realised how low the balance was getting.
