Take the freaking sunglasses off!

The other day, a client came in to look at our furniture for the third time. She was about to place an order. It was 10:30am. She was wearing her "Bug Eyes" dark lenses sunglasses the whole time. It was so difficult to talk to her. Where was I supposes to look? Her nose? Or forehead? It was impossible to make 'eye' contact. How was I supposed to close a sale?!
