The flavoured vodka in the Qatar business class lounge, that's what.
And we had just enough time today, after a short shop and long lunch at a restaurant with a great view of the city, to enjoy the facilities before piling into the aircraft and heading back to Doha.
I couldn't pick the actual flavours, but a shot certainly warmed my toes quickly after we slogged through the snow to get to the terminal.
The weather caved in before our departure, with a blizzard settling on the Polish capital, and the pilot had to taxi to the far end of the tarmac to have the flight surfaces de-iced before we could rumble down the runway.
So it was a smooth flight all the way to Qatar, and that's just the way we like it.
