Purpose Off-premise restaurant service has a new addition – food delivery robots. This new technology and off-premise service, in general, has received little research attention, despite continued year-over-year sales growth for both carry-out and delivery. Therefore, this study aims to analyze off-premise service modes, including food delivery robots, for service quality gaps between consumer expectations and actual performance and among the various modes. Design/methodology/approach Performance of three off-premise restaurant service modes (robot-delivery, human-delivery and carry-out) were evaluated using a mixed-methods approach. Consumer expectations were ascertained about food- and service-related performance factors using a survey, and a field observation study was conducted to obtain actual performance data for these factors. Findings from both approaches were compared to identify gaps and differences. Findings For food-related performance, consumers reported lower expectations for food safety and food quality from robot- and human-delivered food; however, no differences were observed among the three modes in the field study. Consumers also expected lower service-related performance from robot-delivery for service efficiency and ease of use (than human-delivery and carry-out) and monetary value (than carry-out). Consumers deemed robots the most sustainable and human-delivery the most convenient compared to other modes – however, not all service-related expectations aligned with actual performances. Originality/value This study was the first to comparatively examine off-premise restaurant service. Identification of a missing link in service gap analysis was among the theoretical contributions of this study. Managerially, this study provides previously unavailable insights into opportunities for improvement for off-premise service and use of delivery robots.

Purpose Drawing on protection motivation theory (PMT) and expectancy theory, this study aims to investigate consumers’ lodging consumption intentions during a pandemic crisis. Design/methodology/approach The research survey was conducted during the ongoing COVID-19 pandemic (August, 2020) in the USA to investigate consumers’ lodging intentions amidst the pandemic crisis. PLS-SEM and multiple regression were conducted to explore answers to proposed research questions. Findings The research finds that, during the pandemic crisis, consumers’ lodging consumption intentions are subject to both their internal protection motivation evaluations and the external prevention practices implemented by the lodging facilities regardless of property types and travel purposes. Notably, the research finds that consumers are willing to make efforts and pay extra for a safe stay at lodging facilities. Research limitations/implications This research contributes to the literature regarding the applications of PMT and expectancy theory from a crisis management perspective, and it provides implications and guidelines to the crisis management practices in the lodging industry. Originality/value The current research examines the specific protection motivation appraisal factors and prevention practices significantly impacting consumers’ decisions in terms of willingness to stay at various lodging facilities (hotels and non-hotel homestay/short-term rental properties) for different purposes (business and leisure) and to pay premiums for a safe stay.
