[Don't be offended Kaiba, just drink up. Let's see more of this emotional honesty.]

Are we making this into a drinking game...? [Quirking an eyebrow at Kaiba's statement, because if they were...... you two can prepare to lose. Then he looks to Yugi and smiles a little surprised when he does drink the whole thing with his own glass on top of it.
What has he started?]

Thank you. [ Atem voices to the waitress, as she brings him a fresh drink. He catches the look but he thinks he has this under control so her concern isn't necessary.] We've never had the opportunity to go out drinking before, have we? [With that, Atem raises his glass and proves that he can polish off a glass himself, though Yugi is one drink ahead of him. Kaiba had offered to pay for this outing but that was before it had escalated, perhaps they should be a little more conservative- since.. admittedly Atem was the only one sans a money making venture]
