Dd is 14 and quite good at a sport. Her coach asked if she wanted to help teach on Saturday mornings for 3 hours as an unpaid job but she’d get coaching training and be put through her basic coaching exams. She’s really enjoying it and wasn’t that bothered about not being paid. 4 weeks ago the coach came and chatted to me at the end with dd standing there. She said that dd is a great asset and the kids love her so she’ll start paying her “a bit of pin money”. 4 weeks on she has received nothing. I feel I should say something but it’s awkward as initially she took it on not assuming she’s get any money. Even if it’s just £5 a week I’m annoyed she said she would give her some money and hasn’t. If IANBU how should I word it?
