This study investigated the effect of logistics and policy service quality on customer trust, satisfaction, and loyalty within the quick commerce landscape in Jordan, with a particular focus on generational differences between generation Y (Gen Y) and generation Z (Gen Z) users. A survey of 719 active Q-commerce users revealed that logistics service quality (personal contact quality, shipment condition, product availability, timely product delivery, and order accuracy) significantly affected customer satisfaction, with order accuracy being the most impactful factor. Additionally, both cash on delivery and order discrepancy handling significantly affected customer trust. Finally, customer satisfaction and trust affected customer loyalty, though in multigroup analysis, their relative importance varies between generations. Gen Z prioritizes speed of delivery and less concern on personal contact with delivery personnel. On the other hand, Gen Y values product availability and cash on delivery more than the younger generation. These findings offer valuable insights for Q-commerce platforms to tailor their strategies to the distinct priorities of each generation and enhance customer trust, satisfaction, and loyalty.

This study investigates the effect of marketing via Instagram on Generation Z’s preference for gyms in Jordan, so it would be helpful for marketers of gyms to be aware of using Instagram to attract Generation Z as their potential customers. Moreover, a sample questionnaire was carried out with 138 respondents, which were mostly female respondents (74%) and male respondents (26%). Additionally, 51% of the total number of respondents were 21-24 years old. Therefore, the data was analyzed by applying various statistical techniques such as Cronbach’s alpha for testing the reliability of the data, and multiple regression using SPSS version 22 for examining the hypotheses. Likewise, the results showed that Instagram and these variables (entertainment, interaction, trendiness, and customization) have an effect on customers' brand choice, but trendiness did not have a significant effect on the consumer's brand choice, but after testing the effect of the brand image, it became clear that it has significant effect, and therefore it was concluded that brand image has an important effect on customer’s brand choice.
