What dining habit do you find most unbearable?

Out of the four options, I think rummaging through side dishes with chopsticks is the most unbearable habit! While the other habits are also quite bothersome, I personally prioritize hygiene, so this action really bothers me. When it comes to side dishes shared among people, digging through them with chopsticks or touching them with chopsticks you've already eaten with is not only unsightly but also feels unsanitary. It's fine to pick out the dishes you want to eat, but I wish people would consider that others will also be eating from the same dishes. Nowadays, many people use individual plates, so if you're a little mindful when serving yourself, we can all enjoy our meals together pleasantly. While enjoying delicious food is important, I believe being considerate of the people you're dining with is equally crucial! It might seem like a small action, but it can cause discomfort for someone throughout the entire meal. I hope a dining culture of mutual consideration takes root.
