The quick rise of food delivery apps (FDAs) has changed how people operate, especially Generation X, which is known for making decisions based on practicality and adopting technology that adds value. The goal of this study was to find out how Generation X customers use FDAs by looking at the roles of Perceived Usefulness (PU), Prestige Value (PRV), and Affordances Value (AFV). A structural equation model (SEM) based on survey responses from 416 Gen X consumers in Vietnam was used for the quantitative approach. The results showed that PU had a big effect on the link between PRV, AFV, and FDA adoption. PRV and AFV had a positive effect on PU, which therefore had a big effect on FDA uptake. These results show how important it is to use personalized tactics to make FDAs more useful and valuable for Generation X. The study adds to what we know about how consumers act and gives FDA providers useful tips on how to keep customers and make them happy.
