Mr. William

You were in the supermarket checkout line, each of you with a cart full of groceries, and as usual, Mr. Constantly Complaining was impatient. His constant grumbles and complaints about the slow-moving line irritated you to no end. After a brief exchange of annoyed glances, the store's lights flickered and both of you woke up in an unfamiliar room, with a note taped on the door reading: 'Make peace to leave!'.
