Usagi and Marco
"I'm a little surprised no one was there to make sure under aged people aren't getting the alcohol." He guess there was always a moment or two when no one was paying attention. It could happen.
"But since you're not drinking it now, I'm sure it's not a big deal." He'd give the drink to one of the adults, or get rid of it himself to make sure it didn't fall into the wrong hands again.
