Tipping is a customary way of showing appreciation for good service in many countries, especially in the service industry like restaurants, cafes, bars, hotels, and more. It's a way to acknowledge the efforts of the service providers and to ensure that they are fairly compensated for their work.
Some people consider it a pet peeve when customers either don't tip at all or leave an inadequate tip despite receiving excellent service. It can be frustrating for service providers who work hard to ensure a positive experience for their customers, only to receive little or no gratuity in return.
It's important to remember that tipping practices can vary depending on the country and culture, and not all establishments have the same expectations regarding tips. However, if you receive good service and tipping is customary in your area, it's generally appreciated to leave an appropriate tip to acknowledge the effort put in by the service staff.
If you are unhappy with the service you received, it's better to address any concerns with the management or staff directly rather than withhold a tip. In cases of poor service, constructive feedback can help the establishment improve their services for future customers.
