One of the issues under consideration is charging the equivalent of "corkage" on the food and drink you bring on board as we have to pay to have it removed: think of it as your contribution to the environment rather than a charge.
Doesn't worry me one iota. I will never, under any circumstances, travel with Ryanair and neither will anyone I know. Even if I didn't get staff rates with my airline I'd rather pay the extra and go with a proper carrier thanks all the same.
I'm firmly of the opinion that their cumulative dodgy practices will end in tears and/or twisted metal one day, and I don't want to be involved in it when it does.
