Yesterday, I wrote a thread about going away with a work 'friend' and had a bit of a bad time. I decided to leave early, and paid for a £90 train fare home. When she drove us to the work event, it ended up being a 6 hour trip. When we arrived, I offered her £40 which I thought would be more than enough for my share. She rejected and said I just fill up on the way back. That's fine I thought.
She text me yesterday very bluntly with the figure of £51.25 with her bank details.I told her surely it would be half of that as I only travelled with her one way up. Her logic is that because we agreed I would fill up on the way back, I should fill up, even though she didn't take me home.
I'm more than happy to pay the £40 for her taking me to the work event, as I believe that covered well over half of our journey, (even with the roadworks) but should I pay the amount she has quoted, even though she didn't take me home?
