My partner and I came to his dad's birthday dinner as he had asked us to come. We could only just afford it but we went for his sake. His horrendous girlfriend sat down at the table and said 'when your dad isn't looking I'm going to ask for the bill and we'll split it between us I want to treat him on his birthday'. So then my partner was put in the awkward position where he felt he had to pick up the bill for the table which included her grown up children! If she has wanted to treat his father why not just pay for him and her children? We knew it was all for show as she never pays for anything and shamelessly pretended to forget her purse when the bill came. In the end my partners dad paid for everything as he always does. Is it just me that thinks this is appalling manners? She's generally bad mannered and a self absorbs person but this incident has really put me off her in another league and I'm wondering if I'm being fair.
