Yes.
I had a brother-in-law that used to ask for money to 'buy diapers' who, instead, used it to purchase pop and cigarettes for himself. Only took a couple of times of that kind of thing to learn a hard lesson.
Next time he asked for money to buy diapers, I took him to the store and bought diapers for his daughter. He never asked for money again.
Reminds me of my brother-in-law. He gave me a sob story about not having any transportation for work so I sold him my motorcycle for $100. You guess it! He turned around and sold it for what it was worth - much more.
