She was oblivious to the fact that she was being watched. Humming a little tune, she finished up the folding and headed back towards the cash register. The store was empty except for that one person who came in, but she couldn't see him anywhere. She wasn't even positive it was a boy. It had looked like one, but she didn't catch a great look.
Leaning against the counter, she pulled out her phone to check the time. Her boss was due back soon. Until then, she was going to be bored. Though, if her manager came back, saw a customer and saw that Katie wasn't helping him/her, she might get mad. So Katie pushed off the counter and set about looking for whoever had come in.
