It is important to interact politely with restaurant servers, regardless of their education level. If you wish to avoid long conversations, here are some tips to try: 1. **Use nonverbal signals**: Express your appreciation by smiling and nodding, but avoid prolonged eye contact. This usually means that you are satisfied but do not want to engage in further conversation. 2. **Speak briefly**: If the server asks you a question, answer briefly and politely without going into further conversation. For example, you can simply answer "very good, thank you." 3. **Focus on your dining companion**: Focus on the person you are dining with and interact with them to reduce the chances of being interrupted by others. 4. **Use a menu or phone**: When ordering or waiting, you can pretend to look at the menu or check your phone to indicate that you are busy. 5. **State your needs in advance**: Clearly state all your needs at the beginning of the meal to reduce the chances of the server asking again during the meal. 6. **Signal to end the conversation**: If the server tries to start a conversation, smile and say "thank you" or "we will talk to you later" to politely end the conversation. Remember to always show respect and appreciation, a server’s job isn’t easy and a friendly attitude will make the dining experience more enjoyable for both parties.
