Valero Fas Mart is known for its friendly and helpful staff, with Tina especially going out of her way to treat customers with respect. While the store does not have a bathroom, there is a Popeyes nearby for convenience. Customers appreciate the overall nice service, though some mention that prices can be a little high. Most staff members are friendly and respectful, but there was an incident where a staff member refused to sell gas to a customer using a $100 bill, which caused some confusion and frustration. The store and parking lot are generally clean and well-maintained. One reviewer noted that the shift starts earlier than 8am, at 6am, and highlighted that a previous complaint about scheduling was based on a misunderstanding. Overall, Valero Fas Mart offers a friendly environment, with attentive staff and a clean setting, making it a convenient stop for gas and snacks.
