It really infuriates me that they have friends like that Peter and Elaine, and seeing tonight's vlog, I understand why they mention them both quite a few times.
To be invited to someone's home and to basically expect to be fed and supplied booze is disgusting, they knew they'd be eating and drinking loads. Yet in return, they bring 1 bottle of prosecco and a opened box of olives as a gift to the host. I'd be absolutely mortified at the thought of what they thought about me as a person for bringing that in return for everything Peter and Elaine provided for them.
I'm not sure if that's just a me thing, but if that was me, I'd be turning up with more than what they had taken.
