Link waved him off. "Don't bother with change, Pruce," he said. "Consider the rest a thank you for being willing to help me out."
When Pruce gave him a side-long look, he made a show of rolling his eyes and huffing. "Pruce, I have over thirty thousand rupees, trust me, I can spare a hundred to pay for the help."
He gave Pruce a chance to finish wheezing. "And to answer your question, only when strictly necessary. It's catching up with me." Smartass grin, back in effect! "I'm over a hundred, I can't do that non-stop like a younger man."
