I See You

Customer: I want this crab leg.  

Me: You have to help me out a little. I can’t see through the case from back here.  

Customer: It’s right here. Where my hand is.  

Me: This one? I can’t see your hand.

Customer: I don’t know how else to describe it, dude. Better figure it out.

Me: The one to the left? Or the right? 

Customer: Left. Sorry. I should have just said that.
