To Cobb, this would just be a pleasant evening; a few rounds with the team on a Thursday night. Everyone had been working diligently for weeks and he thought knocking a few drinks back would up morale. What he didn't think about was:
1) Ariadne can't hold her liquor.
2) Yusuf REALLY can't hold his, and reduces to a giggling mess after a single shot of whiskey.
3) Eames loves high school party games—mostly because he knows Arthur despises them.
4) Everyone on the team is hot for at least one other person.
So, when he swipes his debit at the local liquor shop, he has no idea that he's bought a night to remember.
