Although you might master the dining etiquette in your country, when you’re traveling to other countries things might get really tricky. Depending on the country you are visiting, be prepared to follow rules that are completely opposite to what means polite at your home.
The differences in dining etiquette around the world may occur in the way you use the utensils or hand, offer tips, share food, or show appreciation. For example if in Portugal and Italy leaving a tip (around 5 to 10% of the bill) it’s a sign of respect, in Japan and China on contrary tipping might be considered rude. If in the western societies belching and slurping during a meal is considered rude, in Japan and China making noise during a meal is a sign of satisfaction and a compliment to the chef.
Even if you might feel strange to do as the etiquette requires it is important to respect the local customs if you want to enjoy your time abroad. On the other side try not be too stressed. Natives know you are a tourist and will understand you. Be opened to learn, have respectful attitude when you make a mistake.
