Clients hate scrolling

Why is it that clients hate scrolling web pages? They seem to make the assumption that users don’t understand how to use a scrollbar, or will think that the content has simply ended mid flow.

I’m assuming that I’m not the only designer to be faced with this issue, how have you dealt with it in the past, and hey, do you prefer paging or scrolling…? Me.., I think scrolling is just fine.
