Context From Original OP:

As Lim Hyeong-su was about to take and drink the poison, he looked at the clerk of the Uigeumbu (State Tribunal), smiled, and asked,

“Would you also care for a cup?”

When someone suggested that it would be better to go inside the house to pass away, Lim Hyeong-su replied,

“I shall rightly die out here under the open sky, where the deities of heaven and earth surround and look upon me clearly. Why should I go to a dark and gloomy place to die?”

Thereupon, he drank the poison and died, and all who heard of it were filled with sorrow.

Considering it is most likely offered by a royal or someone of high rank, would it be rude of the low ranking official to refuse?
