Cultural Tip
German speakers often use short, direct imperatives for safety warnings, especially among friends or in informal settings. In a formal context (e.g., a security announcement) you would use the polite form ‘Bitte passen Sie in Menschenmengen auf.’ The phrase works across all German‑speaking regions, but in Austria you might also hear ‘Sei vorsichtig in den Menschenmengen.’
