During those same travels, I was sometimes together with a friend on those flights.
Visiting for 3-4 mins the lounge just to grab a drink, there was a guy Robert, promoted to squeeze oranges.
My friend tapped on the back and say: how about you prepare us a drink. We shall be back soon.
When we walked in a few hours later, he must have thought we've been checking out the duty free for a while, when in fact, we have been in the meantime 2x in ZRH and 1x in CDG.
