On some formal occasions, leaders generally don't add water or other drinks when speaking. This is because leaders need to keep their thinking clear and express themselves fluently when speaking. If you often add water or other drinks, it may distract the leaders and affect the effect of the speech.

However, in some informal occasions, such as symposiums and seminars. , you can consider adding tea and water to the leaders. This can not only reflect the enthusiasm and thoughtful service of the organizers, but also create a more relaxed and comfortable communication atmosphere for the participants.

It should be noted that when pouring tea and water for leaders, we should respect their personal habits and preferences. If the leader has special requirements, such as drinking hot water or cold water, or without sugar or milk, you should try your best to meet the leader's requirements. At the same time, we should also pay attention not to interrupt the leader's speech too much, so as not to affect the coherence and effect of the speech.
