*edit - ignore me if you are referring to VA instead of QF as per your previous post.
Odd - I fly that leg frequently and haven't encountered the mousse yet! (Not that I'd eat it of course )
*Edit re: mousse sorry if you were referring to Virgin, I assumed QF.
Sorry both - referring to Virgin both cases.
