What sort of environment was he working in, where simply not wanting to talk about a private matter got that much of a ... tantrum? Percy had already made it quite clear he wasn't interested in hearing about the Quidditcher's sex life, especially if another man was involved.
"Somehow," he drawled in response to Oliver's remark, then opened his mouth to acquiesce - to empty air. That was an annoying habit. Rolling his eyes, he followed suit, reappearing in front of the Leaky Cauldron. "Fish and chips, correct?" he verified, finally catching up to Oliver.
