Our 'no-drop' running group waits for me, then speeds away. Is that still a beginner-friendly run?

At the second junction, I caught up to the group just as the leader said, "Everyone here? Great, let's go." I hadn't finished my sentence before they were running again.

The listing called it a social five-kilometre park run where nobody gets left behind. I told the leader beforehand that I usually run around 7:20 per kilometre. He said that was fine. Most of the group then settled nearer 6:15. They waited at turns, so technically they never lost me, but I ran alone between them and arrived as their breaks ended.

When I asked whether anyone could run alongside me, the leader said he already gives his Saturday morning to organising and can't promise a personal pacer. I hadn't thought of it that way. I don't expect ten people to change their whole run for me. I was hoping the social part included more than seeing everybody at junctions.

The route is a familiar public park loop, and I can complete it independently. Should I ask them to publish a pace range, suggest a separate slower group only if somebody volunteers to lead it, or accept that their version of no-drop means regrouping rather than running together?
