When I read AKL HKG, it reminded me of a time when I was the first to board and my seat was next to a magazine rack. The FA then grabbed the only car magazine and stashed it somewhere, I guess for himself. I distinctly remember that flight as the service was below average for NZ.
On other flights, I have seen FA eating salad out of a Tupperware, food brought from home.
And after another flight, the MAF/customs dog picked out a FA. Turned out to be an empty Tupperware but unwashed.
