Tony jumped up more quickly than might have been expected of someone who was so accustomed to the celebration coming to him. Not that he'd ever shown the least reluctance to make himself a drink the second he wanted one, but neither had he ever been shy about asking - or just assuming it would come his way when the right cues were dropped. Jarvis' evident pleasure in his work was definitely the deciding factor. Seeing him openly engrossed in what he'd made was more than enough cause to haul himself out of his seat.
"It's never too late to start," he said, disappearing out the door with some of that nervous energy still propelling him little frantically down the hall. He'd shake it off in a few minutes - now he was just pleased, and happiness in combination with alcohol was rarely an exercise in moderation, for him. (Not that many things were.) Before long he'd probably be steeped in his usual lethargy, forcing himself minute by minute to plow through the work he was actually required to perform, making it more and more difficult for himself with both liquor and fatigue as the almost overwhelming weight of how much he didn't care dragged behind him - but for now he could just get a nice buzz going, and for good cause.
What said good cause? He eliminated half the stock in his bar as a little too businesslike and utilitarian, or too weighty and formal, or overly complex and esoteric for someone who didn't, as he'd said, have a lot of practice - before remembering the not-altogether-incidental fact that he also didn't have a fucking tongue. Anyway, you didn't mark occasions with things that mattered because someone else said they did, because they were expensive or rare or fashionable markers of taste. You did it with things you would remember. Things that were different.
So when he came back to the workroom it was with two beers - decanted into glasses, because he wasn't a complete animal, but sans tray or other ornament. He set them on the table with a flourish - and then, as an afterthought, grabbed that bunch of papers, dropped it back on the table top, and repurposed it as a coaster. It was the most use it was likely to see in a while. He sat, took up his glass, leaned back, and, probably out of deference to Jarvis, did not put his feet up. But it was a pretty close thing. "There," he said, smiling with no small amount of pride. "Easy. Cheers to you."
