I have met several people from Colombia who habitually use "usted" to everyone all the time; I have also met several people who habitually use "tú" with some people and "usted" with other people.
I asked some of them about it. From the answers I received, it appears that whether a particular person uses only "usted" or uses both "tú" and "usted" partly depends on the part of the country they are from and partly depends on the customs of their family.
Talking with people whose habitual usage is different from one's own rarely causes misunderstandings; most people have no troubling figuring out what the other person's habitual usage is and accepting it in good faith without comment.
