Could not get return legs' boarding passes despite trying at every juncture (OLCI, Outstation check in, lounge in HK). RUH immigration (both directions) was very efficient (negligible queue, for entry notably because most people travelling to RUH seemed to be either citizens or reentry on work passes and use the corresponding queues) and security was efficient (5 min queue). At RUH check in agent's questions were overruled by check in supervisor, supervisor said people can fly for whatever reason they like it's not our business.

Note: Lounge has showers but they don't provide towels, bring your own.
