Is There a Man in the Store?

Two men walked in and immediately gave Sarah the creeps. They were significantly larger than herself and wore all black clothes with their hoodies pulled up, literally textbook bad guy clothes. After about five minutes she began getting at a strong feeling that someone was staring directly at her. She quickly turned around to find that one of the men was standing across the aisle from her, holding his phone up in a way that made it very obvious that he was taking photos of her. As soon as they made eye contact, he turned around and sped walk out of the store as though he knew he'd been caught.
