Which term is used for money given to service workers beyond the cost of service?

The term that describes money given to service workers beyond the cost of service is gratuity. Gratuity, commonly referred to as a tip, is an acknowledgment of service that is discretionary and typically given in appreciation for good service in fields such as hospitality, dining, and other personal services. This practice encourages excellent service and allows customers to express their satisfaction directly to the service worker.

In the context of consumer rights, understanding gratuity is important, as tipping practices can vary based on cultural norms and legal standards. It is a way for consumers to directly influence the earnings of service workers.

The other terms listed do not capture the same meaning. A discount refers to a reduction in price, not additional money given. Commission relates to payment based on sales performance, which is not applicable to tips. A service charge is a fee often included in the bill for service, rather than additional gratuity given voluntarily by the consumer.
