服務補救矛盾這項奇特的現象－經歷失敗與補救後的顧客，竟然會對服務廠商更加滿意－顯示出顧客在補救後的滿意上升程度會高於沒經歷過失敗的滿意程度。而雙重偏差，則是顧客再經歷服務失敗與差勁的補救後，對於補救後滿意下降程度高於失敗後的下降程度。這兩個現象都表示出顧客對於補救在意的程度高於對服務失敗的在意程度，剛好也可視為一種對稱性的現象，兩者皆發生在顧客經歷偏離的服務事件之後，導致顧客對於補救事件的評估放大。而本研究主要目的在討論是否會有其他變數影響到這兩個現象的發生，也就是探討這兩個現象有那些邊界條件存在，並瞭解邊界條件是如何影響這兩個現象。
本研究採實驗法進行實證，以餐廳的連續服務事件作為情境設計，設定簡餐店的送餐與結帳情況為實驗情境，探討消費者在經歷偏離預期的服務經驗後，是否會對第二個服務事件的評估更加極端，並將「先前偏離經驗」、「服務預期強度」和「長、短期滿意度衡量方式」三個邊界條件加入架構中探討。
　　本研究發現顧客在經歷服務失敗後，對於好的補救確實有較極端的評估。此外，並發現有無先前偏離經驗並不會影響對後續事件的評估強度。其次，對於服務預期強度較強的顧客來說，預期偏離的效果越強，導致對補救的評估也會越極端。最後，本研究也發現長、短滿意度衡量方式也會影響顧客評估的極端性，使用短期評估的方式較容易導致顧客對補救有極端的評估，長期之下，顧客做整體的評估時，對服務事件偏離預期的效果較弱，導致評估較不極端。

“Recovery Paradox” (RP) means that customer who experienced a service failure and a superior service recovery were more satisfied than the customer who didn’t experience a service failure. Furthermore, “Double Deviation” (DD) means that customer who experienced a service failure and a inferior service recovery were more dissatisfied than the customer who didn’t experience a service failure or just experience a service failure. These two phenomena imply that customers pay more attention on the recovery than on the failure and that the evaluation of recovery is boosted by the initial failure. This study aims to discuss the boundary conditions in which the RP and DD are more likely to occur.
This study uses experimental design to examine the boundary conditions of RP and DD. Experiment scenarios were composed of a series of service event in a restaurant. And the experiment wants to examine whether the customer who experienced the service failure would magnify the evaluation of recovery. Moreover, the experiment also wants to examine whether there are other factors affect the occurrence of these two phenomena. The previous failure experience, the strength of service and the measurement of satisfaction were included in this study as potential boundary conditions.
The result supports RP, but doesn’t support DD. And the result shows that there is no significant effect between the satisfaction and the previous failure experience. Beside, the strength of service and the measurement of satisfaction have effect on recovery satisfaction.
