Who on earth is 281?

Jimmy rested in his hotel room for a while before heading out to Justin's bar. He had been in a bad mood since yesterday and really needed a drink to relax.

Jimmy: "Hi, Justin."

Justin was busy arranging bottles behind the bar with his back to the door. Hearing his name, he turned around to see Jimmy wearing a cowboy hat.

Justin, quite surprised, said, "Jimmy, what brought you back?" After a short pause, "Because of Chief James's incident?"

Jimmy nodded. He wasn't surprised that Justin guessed—the news of James being shot was no small matter. If Justin hadn't known, it would mean he was failing as an informant, especially with his bar located right next to the county police headquarters.

Jimmy: "Give me a drink, anything will do."
