Gratuity practices refer to the custom of giving a tip or extra payment to service workers for their services. This is common in industries like hospitality, where customers often leave a percentage of their bill as a token of appreciation for good service. The amount can vary based on the quality of service and local customs, typically ranging from 15% to 20% of the total bill. In some countries, gratuity is included in the bill as a service charge, while in others, it is entirely optional. Understanding local tipping customs is important for travelers to ensure they show appreciation appropriately without causing offense.
