Describe what you can do
Distinguish everyday conversation from reading complex documents or handling detailed service questions. Requirements vary by venue and clientele. Ask which languages are useful for the specific role instead of assuming that every nightclub needs fluent English or several foreign languages.
Prepare recurring situations
Practise greetings, asking for clarification and passing a request to another staff member. If you miss part of a question, say so. Do not improvise prices, conditions or translations that could create misunderstandings; a short accurate sentence is better than a confident guess.
Keep access to support
Find out who can help when language makes an interaction difficult. Different languages do not justify offensive behaviour or unwanted contact. The same professional boundaries apply, and you can end an inappropriate conversation and involve the supervisor whenever the situation requires it.
