The term "tip money" refers to the small amount of money given to service workers, such as waitstaff, hairdressers, or taxi drivers, as a token of gratitude for the service they provide. Tipping is customary in many cultures as a way to reward good service, and the amount varies depending on the quality of service and local customs.
The word "tip" in the context of giving gratuity is believed to derive from the 17th-century slang term "tip," which meant to give or to pass something, possibly tracing back to an abbreviation of "to insure prompt service." The concept of tipping has evolved over time, gaining commonality in various service-oriented professions.
