And then, a moment later, her brain catches up with what's happened and she jerks back, embarrassed.

"Uh wow, sorry about that. I really didn't, um." She retrieves her glasses from where they'd fallen, sheepish. "If I drooled on you, I guess I owe you two drinks, huh?" She tries to make it something between a joke and a genuine offer - she's not yet sure whether the nearest shoulder is actually annoyed or not.
