I would be pretty annoyed if I thought that any of those appointment slots were filled by WP's and non-status guests flying purely domestically between SYD and MEL whilst I'm on a long haul to LHR or LAX.
Don't think that and you won't be annoyed.
I thought as much ... that you would avoid my first question in having no evidence whatsoever about JQi dom pax in the F lounge. Not your fault in not having the proof though - it's not like you manage the lounge and have access to pax details.
It would be frustrating to have nothing to support an emotionally fabricated and arguably less probable idea.
