Michael O'Leary being incredibly rude is a key part of Ryanair's branding. If you're paying £19 for a two hour flight, you'll always have the sneaking suspicion that the airline is skimping on maintenance. O'Leary makes it absolutely clear that they save money by treating their passengers like cattle. He carefully cultivates the image of a man who utterly despises his own customers, but is far too miserly to allow an aircraft to crash.
