I had a spa day booked for two and the other person couldn’t come so I asked a friend. She didn’t offer anything , we went for lunch in a pub first and not even an offer if buying me a drink. When we were leaving she asked me how much the car park was and I told her it was £12 , she offered to halve me , I told her no she didn’t need to . This particular person has always been ‘careful’ with money so I wasn’t surprised . All in al she had a lively spa day that cost me well over £100 and thought £6 towards car parking was a good offer. lol
