The best way to do business with a liar is confront them with the truth. Tell them that you do business as a partner. If your lying customer still can't see the light, tell him that you may not be the best choice for business, and that you think you have someone that can serve him better. Then, refer him to the competitor that you hate the most.

This is the most powerful question because it not only gives you top of mind awareness (the customer "hot button"), it also tells you their attitude towards it.
