In fact, the terms and conditions do say that dress standards must be at least "smart casual". The issues are:
a) what does that term mean?
b) are lounge staff enforcing it?
And that's where this whole, enormous thread started!
I think the term "smart casual" is well understood by everyone. I think those that decide to "flaunt" this because they "just can" or can't/don't read the t&cs are either slobs or attention seekers, neither of which are society groups that I care to mix with.
This is why, in many instances I fly Q (which is every week) I tend to miss out the lounge completely and just go and get a decent cup of coffee at the gate. In fact if I am travelling on holiday and am wewaring coughpy clothes I won't go to the lounge anyway as I know I don't meet the dress code. Thats called respect I think - another thing lacking in the slobs and attention seekers.
Perhaps its breeding?
