"I'm only telling you just in case, but, everyone at this auction is a big shot one way or another. Don't. Offend. Anyone. Here, the rules are like this, if another bids after you do even though it seems like..." Rolf took his time to explain to the best of his ability about everything Ezra needed to know before they reached the auction building. It was a rather nice expensive restaurant at a top floor in an expensive looking building also.
On getting there, Ezra and Rolf exited the car while the driver drove off. He wasn't going with them. They reached the entrance, and were simply asked to provide the card they received earlier. After verifying, they could enter. These cards were their identity while inside the auction.
