Search Results: letting her down

My 18 year old daughter is getting her very first job working as a waitress at a retirement home. They are paying her $9.50 an hour plus if she gets tips she can keep those. She will work 8 hour shifts - Monday -Friday (40 hours) and the next week will be Monday-Saturday (48 hours) and it alternates every two weeks. She would probably bring home around $400-500 every two weeks. I will have her pay for her phone bill (it’s currently $50) and make monthly payments for her car insurance $100. She will also have to buy her own food. The grocery store down the street would not be a good choice because it’s a rip off and they way overcharge everything. We have spent almost $200 plenty of times on just food for dinner that night. We are letting her live here rent free until she turns 21. She chose to work full time instead of going to college. I am loaning her $100 for her checking account that she has to open (that’s the minimum to keep account open) which she has to pay me back. With her first paycheck she will owe me $250 which then she would have around $150-250 left for spending. She wants to go to Walmart tomorrow and buy food (last time we went she got a ton of food and I spent around $180 and it lasted her about two weeks). I’m wondering if it would be a good idea to add that onto her first paycheck for what she owes me. She gets paid every two weeks. She doesn’t have to pay for gas (we are sharing the car and I’ll pay for it), rent, electricity or water bills. Literally only her phone bill, car insurance and food. Should I make her pay back for the food I buy tomorrow or just let that be the last time I buy her food and from now on if she wants food after this she will pay for it?
