This study assessed customer perceptions of service quality at two retail stores, Delfino's and Caculo, using the SERVPERF scale. Data was collected through an online survey of 80 customers measuring tangibility, reliability, responsiveness, assurance, and empathy. The findings showed that tangibility, responsiveness, and assurance were the most important factors for customers and that Delfino's performed better than Caculo on these dimensions. However, the study had some limitations like a small sample size and potential biases in customer responses.
