Disappointing Auction House

Let me see, an old man is dissing me right from the start. 

The guild master intervenes. 

"Now, now. No need to doubt him that much. He's simply here to appraise the rocks." 

"*Snort* What good is he if that's all he can do?" 

I want to refute that, but he has a point. 

All I really have going for me is X-ray vision. 

I have no idea of the exact market rate or anything. 

Still, I'm able to judge by the look. 

I can just describe everything I see to them worst-case haha. 

They'll be able to tell me the price. 

[What good? I can tell you what anything contains with a look. If that is worthless to you then I may as well leave.] 

"Can you really do that?"

[Yep.] 

He takes a ring he is wearing and puts it in one of his hands. 

"Which hand?" 

Are you kidding me?! 

This is his test?! 

I point to the right one.
