Update:
1.The dad and I had a talk. He is well aware of his son's incompetence.
2. I will bill him for being late. I started today, he was 10 minutes late and .2 went on his bill.
3. I will be occasionally using a hood for which he agreed.
4. I will no longer spoon feed him.
5. I can no longer tolerate his tardiness so I will have to be more firm with him, if not I am actually considering of canceling a lesson in which he was late in the future.

It is a working progress. In a perfect world sure I would love to get rid of him. The reality is that there are and will be students like him in any CFIs career. I am in the opinion that we as CFIs should find ways, sometimes creative, to work such things out. After all we are known to have a great deal of patience. But honestly in this case it is running out in a hurry.
