Measuring devices should be used when serving drinks to ensure profitability and compliance with service policies. Using a measuring device helps control the amount of liquid being served, ensuring that customers receive the correct amount of drink and preventing over-pouring. This can help maintain consistency in taste and quality, which is important for customer satisfaction. Additionally, using measuring devices can help with inventory management and cost control, as it ensures that the correct amount of ingredients are being used, preventing wastage. While options A and D may also be true, they are not the main reasons for using measuring devices when serving drinks. Option B is incorrect as measuring devices are used for practical purposes, not decorative. Hence, option C is the best answer.
