Recognise the limit
You do not have to accept insults or repeated personal requests to appear polite. A short, clear response can explain your role without revealing private information. Avoid entering an argument about whether your boundary is reasonable; the focus is on ending the unwanted interaction.
Use the right support
Questions about prices, bookings or rules belong with the responsible member of staff. Do not promise exceptions or try to manage aggression alone. If possible, move to a safer place and seek help. In an emergency use the appropriate emergency services rather than relying solely on messaging a recruiter.
Follow up on the incident
When it is safe, explain the essential facts to the supervisor and ask what will happen next. Avoid posting guest information online. Before another shift, clarify who you can contact and what practical arrangements are in place if a similar situation occurs again.
