It is recommended to always be polite and respectful. Regardless of the other party's education or work background, they are all providing a service. If you want to reduce small talk, the following methods may help: 1. Respond to questions with short and polite answers, such as "Sorry, I'm a little anxious now." This shows your attitude without being rude. 2. You can look down at your phone, read a book, or put on headphones to make the other party think that you are focusing on other things, thereby reducing the chance of conversation. 3. Maintain appropriate eye contact and body language, such as smiling and nodding, but do not take the initiative to start a topic, which is friendly and will not lead to a long conversation. 4. If the conversation cannot be avoided, you can end the conversation at the right time and say "Sorry, I'm afraid of delaying my trip. Let's talk next time." This method not only buys time for yourself, but also does not make the other party feel ignored. Remember, handling social situations with ease and politeness helps maintain a harmonious and respectful public space.
