The behavior of US CBP seems reasonable to me. The traveller gave an incorrect address and so they sent him to the secondary inspection to clarify things. Bette

The behavior of US CBP seems reasonable to me. The traveller gave an incorrect address and so they sent him to the secondary inspection to clarify things. Better than slowing down the whole queue of people waiting for primary inspection. And the 30 minutes waiting time for secondary inspection also doesn't sound bad. If a 30 minute delay makes you miss your flight, you've been late already anyway.
