Sherlock rummaged around in the pocket of his coat, pulling out a small bag with coins in it. His parents had given him a small amount for food on the way there and then he'd managed to steal some off Mycroft, so he had plenty. "I'll have a box of every flavoured beans, two cauldron cakes, two pumpkin pasties, a bag of jelly slugs, two liquorice wands and six chocolate frogs." He quickly counted out the money, quite thankful that he had enough, and handed it over to the lady. He took the food he was given and place it on the table next to the window. He pushed one cauldron cake, a pumpkin pasty, a liquorice wand and three of the chocolate frogs over to John's side, taking his own and leaving the beans and jelly slugs in the middle for them to just take.
"Most of it is good, but the chocolate frogs hop about a bit so make sure not to lose them... Also there are some pretty nasty flavoured beans so I'd be wary..." He trailed off, taking a bite out of his pasty. He was surprisingly hungry, something that didn't happen too often. Sherlock wasn't one for eating for the sake of it. Slowed him down so he only really did it when necessary. Now seemed necessary. He was eating with John. And he had bought John food, which made him feel good. He had decided not to commnt on the fact John didn't have money... It was probably not the best thing to talk about. Sherlock, after all, was pretty well off.
