Here is my situation: I'm not a pro stringer by any means, and i dont have that much experience. I can string my own racket just fine, but dont have any experience with other rackets like I said. Long story short, I strung my friends racket badly and I feel bad about it. The racket will still play fine and everything I'm sure, but I think I skipped the wrong holes or something and you can definitely tell its not done 100% correctly. The strings were $15, and I really dont want to charge my friend for a bad string job. I should never have agreed to string his racket in the first place. My dad on the other hand says give him the racket and see what my friend says. He wants me to charge him. What is the right thing to do? I made a mistake and dont want to lose the guy as a friend, and the racket is playable. Help ?:?
