I thought it was a very good episode for him. Aisleyne wrecked my head with the horrible way she was speaking to him like he was dirt.
I know she was playing the role of a "guest" but so were the others and they managed to retain their manners and say please and thank you and not act like complete dickheads. Even Charley seemed embarrassed by Aisleyne's behavior and apologised in the bedroom to Jack on behalf of Aisleyne (even though it wasn't her fault her friend was behaving like a cow).
Jack handled it all very well and kept a smile on his face, even when faced with the dreadful task of touching John's feet and back!
After watching the episode I can sorta see why he is a manger and think he s probably very good at his job in real life.
