Betty Booperbottomwas under-the-weather after having her appendix removed. She asked her neighbor, Slippery Pete, to help her with her groceries, lawn, and most importantly, picking up her prescriptions. Slipper Pete, who goes by Slippery for short, agreed. A few days into helping, he said to Betty, "I am doing a lot of work here. I know it's a favor, but I think you should remember in a big way in your will. If you can't, I think I may be too busy to help you anymore."

What is wrong with this statement by Slipper?
