Summary	A mystery shopping audit measures how service is actually delivered by sending trained assessors who pose as ordinary customers to experience and objectively record a service encounter against predefined standards. Alan Wilson's 1998 work set out how this covert method differs from satisfaction surveys: rather than capturing what customers feel, it captures what frontline staff and facilities actually do, scored against an explicit checklist of observable behaviors and conditions. Because the assessor is incognito, the audit reveals the routine, unguarded service the typical guest receives. The approach draws conceptually on service-encounter research such as Bitner, Booms, and Tetreault's study of the specific behaviors that make encounters favorable or unfavorable, grounding the audit instrument in the moments that matter most in hospitality.	The hospitality critical incident technique studies service quality by collecting and analyzing concrete accounts of especially memorable service encounters, the moments guests recall as outstandingly good or bad. The technique itself was formalized by John Flanagan in 1954 as a set of procedures for gathering direct observations of behavior that are critical to an outcome and classifying them into meaningful categories. Bitner, Booms, and Tetreault adapted it to services in their landmark 1990 study, collecting hundreds of incidents from airline, hotel, and restaurant customers and sorting them to reveal exactly which employee behaviors separate very satisfying encounters from very dissatisfying ones. Applied to hospitality, the method turns guests' vivid stories into a structured map of the behaviors and conditions that drive satisfaction and dissatisfaction in the service encounter.
