Answer

Brief Explanations:

The nutritionist surveys only customers from a local coffee - shop. This sample does not represent all Americans as it excludes those who do not visit that coffee - shop. It is a form of undercoverage bias where parts of the population (non - coffee - shop customers) are not included in the sampling frame.
