The Avengers: The Heli-Carrier is Always Prepared for Fine Dining

So, here we have Captain America looking stern, yet confused, ...wait? Is that a glass case of fine china behind him? Now I'm confused, why is that there? Does S.H.E.I.L.D. host many stately dinners on the heli-carrier? I thought it was supposed to be a secret. Did they just have left over money in the budget and decide, "what the hell, let's buy some fancy plates!" Or, do you expect me to believe that S.H.E.I.L.D. commissioned as series of commemorative plates? -JH
