What did Troy Smith believe every guest was worth?

Troy Smith believed that every guest was worth a mint, which signifies a gesture of appreciation and value towards the customer's experience. This notion reflects an understanding that customers are not just transactional entities; they are individuals deserving of recognition and gratitude for choosing Sonic. By associating the worth of a guest with a mint, Smith emphasized the importance of making customers feel valued and special through small gestures that enhance their overall experience. This practice is in alignment with creating a welcoming and attentive atmosphere, often translating into customer loyalty and positive word-of-mouth—vital components of a successful service-oriented business like Sonic. The other options, while they pertain to gestures of appreciation, do not resonate with the same level of symbolism attributed to a mint in conveying simple yet impactful customer appreciation.
