Rand and Mat want to stay at his inn, but they are shocked when they hear the price of a room for the night. Master Allwine tells them that everything costs five times as much as it used to and that the prices are still rising. His neat appearance makes Rand trust him and neither he nor Mat want to sleep under a hedge again, so they are willing to pay.
