Why did Gaius and Merlin think that the Sidhe would help Arthur, even if Merlin was able to get him to Avalon on time?

In the past, the Sidhe were going to accept Arthur as a sacrifice or to have him marry a princess possessed by a Sidhe. They seem to have quite a healthy disdain for mortals as a rule. You'd think that they'd refuse to help or, at the very least, exact a very heavy price for their assistance.
