Graduation cake conundrum
Hi. My sister in law graciously agreed to bake my daughters graduation cake. It was 2 tiered and decorated beautifully. She also added 72 cupcakes. She did an outstanding job and it tasted delicious. She shrugged her shoulders when I asked her how much she would charge. She said I could just reimburse her for supplies, but I know there was substantial work involved. She also gave my daughter a monetary gift. I want to thank her and pay her well for her work. What do you think I should do? How much should I pay her?
