Draco actually snickers, and there's a hint of a grin in his smirk. "Occasionally."

When he looks again, Billy is looking at him, and he blinks a moment and sets the drink he was about to sip back onto the tabletop without actually bothering to do so. Which is probably good, he might have spilled it otherwise when he feels a hand on his leg. It only takes him a beat to recover from the surprise, but it was definitely there, illustrated by a slightly sharp intake in Draco's otherwise steady breathing.

He exhales, his eyebrow quirking slightly again as Billy surveys the bar, and then, since it's right there in front of him, Draco leans in to brush an answer just beneath his ear. He's not feeling particularly inclined to hold back. "That depends entirely on how much trouble you think we can get into back here."
