Percy didn't often leave the office for lunch. Not out of some overdeveloped sense of responsibility; he simply got focused on his work and forgot to leave. He'd never had that large an appetite anyway, after growing up in a household where money was sparse but children were everywhere.
Today, though, it was hard to focus on his work, and easy to grasp for a reason to leave. Ever since he had returned a potentially harmful antique to Luicus Malfoy despitethe protest of the auror department, Percy had become something of a pariah. Nothing new there, of course, but it was less comfortable to be regarded an outcast for possibly arming a Death Eater than it was to simply be regarded as irritating and odd.
So. Lunch. There was a strip of road beyond the Ministry with a few food shops. Popular with Ministry workers, but he could be assured that if anyone who currently hated him spotted him, at least they were likely to behave in a public place.
He hardly looked around as he walked, not wanting to daw attention to himself, and had his head low and his hands in his pockets as he ducked into a small pasty shop.
