Wow - all that says to me is that Wizz is not a serious entity.
It screams 'we want stag and hen parties on board our planes'. This comes at a time when resorts in the Med (Spain most recently) are actively trying to discourage the 'trash' end of the market.
The only time I've used Wizz was a one way flight between Germany and Belgrade and there was nearly a full-on fight during the flight between a group of Germans and some Dutch guys. There was a huge amount of verbal alcohol-fuelled aggression, exacerbated by the crew irresponsibly selling them more, continuously.
Fully expected the police to board on landing but it didn't happen - I read that as saying 'this kind of thing is ok / normal on our flights'. Needless to say I've avoided them since.
