The method of eavesdropping is not suitable for determining customer satisfaction with meals because it typically involves listening in on conversations without the participants' knowledge or consent. This approach raises ethical concerns related to privacy and respect for individuals' rights, making it an inappropriate method for gathering feedback in a customer service or dining context.

In contrast, comment cards or surveys, observational surveys, and plate waste studies are all legitimate methods for assessing customer satisfaction. Comment cards and surveys allow customers to provide direct feedback about their dining experience. Observational surveys can provide insights into customer reactions and behaviors during a meal, while plate waste studies involve analyzing leftover food to infer guest satisfaction concerning portion sizes and meal quality. These methods respect customers' rights and typically gather data in a more acceptable and reliable manner.
