Well, if you're used to "uncivilised travel behaviour" then you'll be well-prepared for the scrum which is boarding a Ryanair aircraft!
Don't get me wrong, Ryanair do what they say on the tin. They get you from A to B cheaply. Not with much comfort or style mind you, but more often than not on-time. At best, travelling with Ryanair is bearable, but could never be described as pleasant. The cattle-herding at boarding, the abrupt (often incomprehensible) crew, the garish aircraft interior, the mess you invariably find since they don't have time to clean the plane on turnarounds, the ridiculous music they play, the cheap plastic seats, the constant sell sell sell with loud announcements, the self-congratulatory fanfare if the aircraft lands on-time (or even 15 minutes late because apparently that's defined as on-time?!) ... and that's if it all goes to plan. Woe betide anything should go wrong, because if it does, you're left up the creek without the proverbial paddle. And that ranges from someone's cabin bag being too big/heavy (when you're stung for a wad of cash), to your flight being delayed or cancelled. And I guarantee you that the day something happens to you or yours on an FR booking, your opinion of Ryanair will change.
