I don’t think it’s to with him paying Elaine invited herself threw a strop when she didn’t like their accommodation and booked her own place, it went downhill from there, eating in expensive restaurants with five courses etc, I think she didn’t like how close Paul and Sandra were and cause he’s a prick he didn’t stand up for her and let her fly home alone, where she looked visibly upset and said we’ll book next time just the two of us day Elaine got in his head and turned him against Sandra as we didn’t see or hear her again when he got home
