72hrs p/w is savage. The most I've ever done was a 300 hour month. There was with a 50 hour shift in with that just for the giggles (2 days straight w/ sleep-in wage ) and I don't recommend it. Someone I used to live with worked at loads of bars, pubs and clubs, and he never left for work before 6pm. I think it might be crossed wires; 12 hour shifts are more common in warehouse/logistics roles so might be stray info about the other job floating around. I hope so for you, sounds like it could be a nice career oppurtunity.
