The leader asks you how to drink and how to answer.
The leader asked how much you can drink. I think you should answer according to your actual situation. Drink if you can. If you can't drink, you can't drink. Don't try to be brave and say that you can drink. If the leader wants you to accompany the wine, you can't drink it. Isn't it delayed? So, just tell the leaders what to drink, and leaders also like honest subordinates.
