Had a spare ticket for a family day out. Invited a friend who has no children to come along to join us on our day out. ( basically I thought I'd have someone to chat to while the kids went on stuff we didn't want to or where to big for).
Part way through the day (just after lunch) she decided she'd didn't want to do what was doing and went off to do something else in the park.
I wouldn't mind too much except she was helping carrying a bag and took it with her so I had no money.
Also She didn't pay for her ticket (or offer any contribution to travel costs, tickets costs)
I made her lunch she didn't bring anything with her food or drink wise but happily ate what I had brought to eat and drink.
She basically came along did what she wanted, for fed and said see you later.
I know she had money as she asked if £60 would be enough for the day. I don't think I'd have even thought about the money if she had spent the day with us but she didn't.
We had a good time anyway but I think it's really cheeky and that if you go for a day out with someone you don't just go off on your own.
