Stand in any checkout line and watch the same exchange repeat with every customer. The greeting. The question about whether everything was found. The comment on the weather or the length of the day. The thank-you, the have-a-good-one, the next customer. The words are not chosen. They are issued. Both people are reading from a script neither of them wrote, and both know the other is reading too.

This is not a criticism of cashiers or customers. The script exists because it works. It moves bodies through a transaction with minimal friction and no risk. Filling that time with genuine, unscripted human contact would be exhausting at scale. The script is a labour-saving device, and most social interaction runs one for the same reason.

The interesting moment is the break. Occasionally someone steps off the script — asks a real question, says something true, makes eye contact that means it. You can watch the other person reboot. There is a pause while they stop running the routine and actually arrive. Sometimes they meet you there. Sometimes they cannot, and the script resumes.

The Codex is not against scripts. It is against running them without knowing. The next time you reach a checkout, notice the lines you are about to deliver. Then decide whether to deliver them or to say something a person would actually say. Watch what happens when you do.
