Cultural Tip
In German business culture, politeness (Höflichkeit) is expected, but it is often expressed in a straightforward, matter‑of‑fact way. Combining it with ‘professionell’ signals that you value both courteous interaction and high standards of work. When speaking to strangers or in formal contexts, use the formal ‘Sie’ form; the imperative ‘Sei’ is appropriate when addressing a colleague or a team member you know well (du‑form).
