Each culture has its own habits when having meals at the table, let us see some habits of Asian cultures.
In Thailand, the spoon is used to take the food to the mouth, and the fork is used to pile up the food. It is a common habit that the first and the second plate are served at the same time on the table, and are shared. Never eat “the bite of shame”.
When you visit Korea, do not forget that you should not start eating before people that are older than you. If someone is older than you who offer you a plate of food or a drink, you should take it with two hands, otherwise, it is considered as a lack of respect.
In China, it is very acceptable that you try every dish that has been offered to you, and leave the last bite of food on the plate, this means that you have been served with a generous meal.
If you visit Japan, apart from that you can arrive one hour late to a meal appointment, never leave the chopsticks vertically stick in the rice (you are offering rice to dead people!). Always leave the chopsticks in a horizontal position next to the bowl or plate (very useful in the most of Asian countries). Slurping the noodles is an act of how much you do like the noodles, and drinking the soup directly from the bowl.
In Afghanistan, if you drop the bread off the table, you should pick it up, kiss it and put it back at the disposal of the guests. It shows that you have respect for the food and the labour that has been employed to prepared it.
In the India, you have to eat everything, throwing food away is a “sin”. Only use the right hand to take the food to your mouth, and try find the balance between eating rapidly or slowly.
