Atton's at the bar, doing bartending, and looking incredibly tired, grumpy and gloomy, and just about glaring at everything that gets in his line of sight. Urahara learned to not let him pick up glasses about four minutes ago. They keep shattering.
Obviously, this will not do. So he has an assistant. Urahara's not quite used to being an assistant, but he's adaptable. And really, since Atton seems to be more concerned with snapping at anyone who talks to him, Urahara's doing most of the 'tending.
"Discounts for all if you can make the bartender here smile," Urahara calls jovially, waving his fan. "Without doing this." And promptly grabs the corners of Atton's mouth, stretching them up to a grin. He manages, somehow, to move out of the way before Atton's fist collides with his nose. "All drinks free if you can make him laugh. Chuckling bitterly doesn't count."
"Specials," Urahara continues, grinning cheerily in response to the withering glare Atton sends in his direction. "Are
Joy-To-The-World and
Happy Skipper."
