Hi, Ive read all the previous threads about the T1 and T3 lounges in Dubai and I know the rule but I was wondering how well this is enforced as far as other airports go?

Last week I flew HKG-DXB-MAN with the latter flight in Business and the former in Economy. I asked at check-in if I could use the lounge in Hong Kong (worth a try), she said no because in economy its "only open to gold and silver members", though I knew the silver part to be wrong it got me thinking. Since Ive taken that flight Ive just moved into silver and I wonder if next time they will make the same mistake? Or maybe it was just the check-in girl making the mistake and the lounge attendant would have known better?

Anyone have experience of this?
