The customer is always right, or is it?

From Clients From Hell:

Client: “We like it, but could you make all the links look exactly the same as paragraph text?”
Me: “Ah, then no one will know they are links, or know how to navigate your site?”
Client: “They will if you make the pointer change when they hover the links.”
Me: “But they won’t hover the words on a page unless they know it’s a link in the first place?”
Client: “Trust me, I’ve been doing this a long time, kid. It’s called SEO, Google will know they are links.”
