Kirley Duke! Jack was trying not to stare, because he was a clever enough lad to know that would be weird. People didn't tend to like being stared at, unless the other person had a glass eye and couldn't help staring. But Jack had two perfectly functioning eyes and thus did not have that excuse. So he made sure his gaze moved around the store, and just glanced over at the famous rock star! in a casual manner. Which probably wasn't working very well. But he was trying!
But the famous rock star was coming his way! Well, was coming the way of the counter, but he happened to be standing beside that counter.
"Hello," he began, but no more words made it out of his mouth before the man was explaining it to him the problem. And, well, as a fellow guitarist, he could understand that emergency! He always kept extra strings for his guitar at home, but he too had run out on occasion. It was quite upsetting!
"Sure - that's a great guitar by the way. We do. Over here." Jack's hands slid over the counter as he stepped around it and started across the shop. "This way. What strings do you need? Particular ones, or a full set?"
