Which textual evidence best supports the conclusion that Arthur respects tradition?

Read the excerpt from Sir Gawain and the Green Knight.

Yet Arthur would not eat until they were all served.

He seemed full of the joy of youth, almost a boy.

He was happy with his life; he cared little

For lying in bed or sitting still for a long time,

His young blood so stirred him and his wild brain.

That he had assumed in his noble way: he would not eat

On such a holiday until he had been told

A tale all new of some wonderful event.
