In-person meet up for Theatr ticket

Hi! I am thinking about buying a ticket to a show from a reseller on Theatr. They claim that there's no digital ticket and that we would need to meet up beforehand and enter the theater together. Seems like a recipe for disaster (scam?!), but also I understand that logistical situations like this can happen.

Does anyone have any positive stories about situations like this on Theatr? Horror stories?? Does anyone know how Theatr handles situations where the seller no-shows?
