I don't think the particpants of this thread have a common understanding of what constitutes 'thongs'. The lounge staff seem to have a good understanding, but it is all the egde cases that people throw up that are causing problems.It's not QF though. They have a dress code that apparently does not permit thongs to be worn in some lounges. The lounge dragons are the ones that are struggling with the term thongs. It seems fairly simple to most and if they persist with the policy (which I hope they do), before long, all the dragons and the vast majority of regular lounge guests will know the expectation.
