That bar is crazy bonkers.
It was called the SMOKING BAR which was not particularly ambiguous. You could smoke in the whole of the back of it.
Then it closed down for a refurb and reopened with a smoking cubicle in the back. Then the cubicle disappeared and it was a no smoking bar, then you could smoke in the back again.
I don't know why I bother with it given I can smoke in either of the VIP lounges.
On a long layover though I prefer to leave the airport and smoke outside with the taxistas. Call me odd but smoking without a bit of fresh air seems somehow "unhealthy"
