Guy's Behavior

Is this considered stealing?

When we need repairs around the house, my dad always asks at least 2 or 3 people to fix it and sometimes he will spend half an hour talking to them and than reject their service without mentioning he hired someone else and when we needed repairs on our roof and the guys worked almost 8 hours, my dad gave them coffee and a tip under 20 dollars for 2-4 different guys for 8 hours of gruelling manual labour, he makes almost as much as a doctor while working less than 3 hours a day and he wants to go on strike because the boss will not give him a raise, and he hated for for 11 years because I got him to pay my tuition and than dropped my classes and he could not get his money back, and he could earn my tuition with 20 days of work at his job - 4 hours a day of work for 20 days would pay it to for but he hated me for 11-17 years because he thought I wasted his money.
