Pay Toilets on Ryanair

Low-cost airline in the UK Ryanair is considering having customers pay to pee, as reported on The Economist's travel blog, Gulliver.I've flown Ryanair, it's a miserable experience (much worse than Southwest), but it is cheap, with frequent flights all over Europe.But I think this is a bad idea. Movie theaters don't have pay toilets because they would probably lose at the box office what they charged for the bathrooms. It's even worse 30,000 feet in the sky with no options.It makes sense to charge for a beverage, checked luggage, and other items to keep down price. But I think this crosses the line of decency.What do you think?
