It’s pretty great when your customer complaint over social media receives a swift, decisive response from the target company. What is not so great is when that response is to boot you and your elementary-school-age children off a plane before takeoff because you complained about a specific employee’s actions over Twitter.

That’s what a Minnesota man says happened to him during a flight on Southwest. The basic facts of what happened are that the dad in this family has earned “A-List” boarding status, but his kids haven’t, so the entire family wasn’t allowed to board early together.

The man threatened to complain on Twitter, then he did tweet about it. “Wow, rudest agent in Denver. [Name], gate C39, not happy @SWA,” he recounted to news station WCCO, trying to remember his Twitter post.

After the family finally boarded, they were asked to get off the plane. The agent claimed that she felt threatened by the tweet. “I like thought something bad was going to happen, like my dad being in jail,” the 6-year-old told reporters.

The family were allowed to re-board the plane once he deleted the tweet. Southwest confirmed that there was a family removed from their flight in Denver for a short time, and that the incident is now “under review.”
