Try it on one of his co-workers

A small smile crosses Jose's face. His thoughts turn to Rebecca, the hot brunette who works as a waitress in the hotel's restaurant. He had asked her out a week or so ago, but she had rebuffed him badly.

"I'm working here to pay for Medical School" she had said coldly "you're a dumb Valet boy. I'm far too smart and good for you" she had declared before turning on her heels, and left him alone and humiliated.

Jose had avoided her ever since. Now with this miraculous device in his possession Jose felt ready to see her again.

The elevator slowed and came to a stop. The 'ping' sound startled Jose out of his thoughts. As the doors opened the newly Asian mother and her son got out of the elevator. The woman smiled and said goodbye while the boy waved at him. As the doors closed Jose pressed the button which took him to the restaurant's level.

Once the doors opened Jose quickly made his may to the restaurant. Rebecca was laying the tables in preparation for lunch. To Jose's delight she was currently alone. With sweaty palms he retrieved the gun from his jacket pocket and turned the setting dial and put the gun behind his back.

Rebecca eventually noticed Jose's presence, turned and sneered derisively "Oh its you! What do you want dummy?!"

Jose turned the gun on her and simply said "this" while pulling the trigger.
