Petro Mart has mixed reviews regarding its customer service. While some employees are friendly and go above and beyond, like the cashier who helped a customer in need by covering the cost of gas, others show less patience, leading to uncomfortable interactions. Customers often experience lengthy waits in line, which can be frustrating. One frequent visitor shared a recent encounter with an employee who reacted negatively when the customer forgot to take their change, leaving them feeling hurt. Despite these mixed experiences, many appreciate the store's offerings and the kindness of some staff members. Overall, Petro Mart is described as a place with potential, but some improvements in service consistency could enhance customer satisfaction.
