Tipping customs can vary from country to country and even within different regions. In some cultures, tipping is considered customary and expected for various services, including restaurant servers. However, the specific situations where tipping is expected might also differ.
In many Western countries like the United States, Canada, and some parts of Europe, it is customary to leave a tip for the server at a restaurant. The standard tipping practice is generally around 15% to 20% of the total bill. This tip is given to acknowledge and show appreciation for the service provided, including attentiveness, order accuracy, and overall dining experience.
As for situations involving extra condiments like salt and pepper, it is not common to leave a tip specifically for bringing these items to the table. The tip is usually based on the overall quality of service during the meal, such as taking orders, refilling drinks, and ensuring a pleasant dining experience.
Remember that customs can vary, so it's a good idea to research the tipping practices in the specific country or region you are dining in. Some countries might include a service charge in the bill, while others may not have a strong tipping culture. Always feel free to ask locals or check local guidelines if you're unsure about tipping customs in a particular place.
