At first, Steve didn't realize the voice was directed at him - but it drew him out of his own head enough that he glanced up, only to discover a petite young woman standing a short distance away, looking right at him. It took him several long seconds to understand to what she was referring, before he glanced down at his cup and muttered a quiet "Oh!" He looked back up at her, dimly noting her nametag read 'Marie', and started stuttering out a panicked reply, as was his wont whenever he was accused of stealing (it happened more often than you'd expect, but usually it was Bucky who'd--no. Not anymore). "Oh, no, I just--that is--"

Then the subtle cues caught up with his brain and his mouth, and he realized she was teasing him. She was doing an admirable job of keeping a straight face, but her lips were twitching upwards. He'd never been good with women teasing him, and definitely not flirting with him (he couldn't be sure she was flirting with him, though; sometimes dames--women--were just friendly), but he tried to be casual and polite and friendly.

"I'll make another one up," he offered, sounding much calmer now. He raised the plastic cup in a small salute and tilted his head toward her. "And I won't tell if you don't," he said, adding a hand gesture to indicate her own glass. Unfortunately, he hadn't drunk a lot of the punch yet, and the gesture was a little too grand, and some of the liquid sloshed over the edge and down his hand, dripping onto the linoleum. Way to go, Steve, his inner voice (sounding very much like Bucky) griped.
