Cultural Tip
In German‑speaking countries lockers (Schließfächer) are common in train stations (Bahnhöfe), universities, and gyms. They are usually rented for a short period and you receive a metal key or a numeric code. When asking about a locker, it’s polite to say "Entschuldigung" first, and staff may reply with the word "frei" (free) or "besetzt" (occupied).
