Always End on a Good Note
If the customer opts to not buy a policy that day, stay polite and try to close out the conversation on a positive. Maybe circle back around to your earlier small talk or wishing the customer good luck in whatever's going on in his or her life.
Sounding irritated or hanging up on them is a guaranteed way to never hear from the customer again. You never know if they will tell friends that you were rude. Word-of-mouth spreads pretty fast, especially now with sites like Yelp and Facebook.
