Several times she has come over to stay the night with me ( I am a single parent) I have suggested takeaway last night so I didnt have to cook but she never contributes.One of my friends also joined us and contributed and left a bottle of prosecco here. She said to me last night she would never ask for paying halves with friends?!
I said to her this morning I will take the bottle back to her and my mum said no you dont do that!
I would always offer to pay towards a takeaway and pay halves for anything brought.
