Are we saying a group B person would only be invited to the reception? I think I’ve been invited to slightly more weddings where I would be in the cut off zone with a limit of 30 guests, which I would think of as group B, but I’ve only been invited reception-only once (to someone I barely knew, but was friends with other people in her friendship group and occasionally got invited to their group stuff. It was in the middle of nowhere and I gave them £20 as a wedding gift. within 6 months she’d unfriended me on Facebook. cheeky cow.)
