Trip Doctor: Room Service Tipping Etiquette
Q: Is the “service charge” on my room-service bill the same as a gratuity?
A: Though the exact definition varies from hotel to hotel, service charge usually indicates a pooled tip, to be divided up by the entire room service department. If your specific attendant was particularly good, you may consider giving an extra gratuity—but are in no way obliged to do so. To be sure, ask what the hotel’s policy is when placing your order.
