One way to practice treating people with respect is by getting to appointments on time or early. When you leave for an appointment, always leave enough margin for the unexpected—which will often happen.
By the same token, always bring something with you to do or to read. I know one man who brought foreign language flash cards with him to reinforce his learning whenever he had times that he needed to wait.
Alternative, you can just enjoy the downtime. Sometimes life is busy enough that it’s nice to be able to just sit and think or pray.
