A scenario played out at my Tennis Club today. I was playing in a Club Day, when my strings broke and I only had the one racquet on me (I have a couple more, but usually leave them at home on Club Days). So, I asked a mate I know at the Club if I could borrow one of his racquets. He said yes. A couple matches into the day, I manage to break this racquets strings. I look at it and it's snapped relatively close to the middle of the head. After the game, I tell him what happened and he says I have to pay for some new strings. I question him, and he tells me that he hasn't restrung for about 6 months. And he plays regularly too. I argue this and he storms off. So what should I do? Pay for them? Or not pay for them?
