Ok so if you and youe partner were going away with another couple and the other woman was main organiser. She had been trying to get reasonable flights etc but was proving tricky. She eventually found flights for a good price and checked with the you if ok to book and it was so she did.
She also checked it was ok to get certain tickets to an event that had already been agreed (including price), and booked these also. So the other woman had paid out almost £700 for you and your partner. She then texted you to say 'yay, all done, flights, event booked etc, looking forward to it etc etc'.
How would you respond?
