Which symptoms may indicate that a customer is experiencing an allergic reaction?

Wheezing or shortness of breath are significant symptoms that may indicate a customer is experiencing an allergic reaction, particularly to food. Allergic reactions can trigger a response from the respiratory system, leading to difficulties in breathing, including wheezing, which is a high-pitched whistling sound, and shortness of breath, where an individual feels like they can't get enough air. These respiratory symptoms are often associated with conditions like anaphylaxis, a severe and potentially life-threatening allergic reaction that can occur in response to certain foods. Recognizing these symptoms promptly is crucial for ensuring the safety and health of customers who may be at risk for severe allergic reactions.
