It's more publicity that RYR don't have to pay for... MOL will be pleased no?!
Whilst I don't necessarily agree with what she said or the way she said it, nobody was harmed as a result, it's unlikely she caused undue concern to any passengers either, mostly they just seem surprised.
But she's obviously not English so it may have sounded better in her head before she translated to a second language.
Sounds like the skipper got on the PA pretty quick but of course the video conveniently cuts out that bit.
