Összefoglaló	DINESERV is a 29-item instrument developed by Stevens, Knutson, and Patton in 1995 to measure perceived service quality in restaurants. It adapts the five generic SERVQUAL dimensions of Parasuraman, Zeithaml, and Berry — tangibles, reliability, responsiveness, assurance, and empathy — to the specific realities of foodservice, where the meal experience blends physical surroundings, the dependability of order delivery, staff attentiveness, the competence and trustworthiness of servers, and individualized care. By administering DINESERV to diners, an operator obtains a structured reading of how customers perceive quality across these dimensions, can locate where the experience falls short, and can prioritize improvements. The scale has become one of the most widely used purpose-built measures of restaurant service quality.	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.
