What happens if someone doesn't show up?

Do these steps at the meeting point. We decide from the RBApp chat.

I'm the host

When you arrive, take a photo of where you are and send it in the RBApp chat with "I've arrived".
Wait 30 minutes after the start time and keep messaging in the RBApp chat. Still nobody? You can leave.
If the traveler asks for a refund, tap Reject in the app within 7 days.
