A-도록
This pattern means "so that" or "in order to," and it is often used to show purpose or to prevent an unwanted result. It is formed with a verb or adjective stem + -도록. In the story, "불편하지 않도록" shows that the staff member chose a solution to prevent discomfort. You can reuse it in situations like giving advice, making arrangements, or describing considerate actions.
