Cultural Tip
In German‑speaking countries it is common to explicitly mention allergies when ordering food. Restaurants often ask, 'Haben Sie Allergien?' and expect a clear answer. Using 'schwere' or 'ernsthafte' signals that the allergy requires special precautions, such as separate preparation or a nut‑free menu.
