  1. Significance: When a waiter gave two candies with the bill it increased tips by 3.3% (compared to no candy) to 14% with 2 candies.
  2. Unexpected: One candy was expected and so when a second was given it inflated the tip.
  3. Personalized: The more personalized the request, the more likely the person will agree. - A recipient places more value on a favor compared to the person who gave the favor initially. However, as time goes on the value decreases in the receiver's mind but increases in the givers. - Before you get to the toughest request (on a call to a customer service agent) tell the person how happy you are with their service and that you are going to write a letter of appreciation. After you have their manager's details, ask for one final request.

9. Trust

10. The Ikea Effect
