I found Zac's "banter" and behaviour actually unpleasant, and very uncomfortable viewing. I wish at least one of the women had said seriously, "that's not ok" and walked off. I understand in the situation they're in that they may feel the need to keep the peace.
I really liked Noky and Chanelle's conversation. Sensible, authentic and balanced - you hardly ever see that kind of interaction on telly or social media nowadays, let alone on reality tv.
