Teaching the value of money and self worth

My child wants to go to the movies with her friend. She’s a great kid  but I’m trying to teach her how to  deal with , problem solving ,and  the difference between negativity and positivity. She has been in trouble with her friend several times in the past. Should I pay for her to go to the movies? Should I have her use her own money even though I stress on saving for a investment? I like teaching and I feel like I’m teaching her a lesson. I still took her to the movies and did not give her money. I called her back several minutes later and she said she was still in the lobby and That she was going to get something to eat. Give me some feedback let me know what you think?
