Close your eyes for just a second and imagine an airplane flight where you had to pay money to use the toilet. The door won't open until you slide in your credit card, or dollar bill or exact change. It all sounds great in practice doesn't it? You are an airline and you know people will use the bathroom so you might as well make a buck off it.
Ryanair, which is one of the largest discount carriers in the world is considering charging people 1 Pound to use the bathroom on their flights. So, let's see, that is about $1.43 here in the US.
So, what exactly happens when the guy who has had four beers in the bar at the airport wants to use the bathroom but the credit card reader can't get a signal, or the machine just won't take your wrinkly dollar bill? Will the flight attendants take mercy on you? Will they have a special area for the people who don't have any money? Will they sell adult diapers for those really long flights where you know you will have to use the bathroom several times?
I predict that within a month, the bathroom door will have been broken down so much by frustrated passengers that the whole idea will just be shelved. Of course just because you are paying the $1.43 for te toilet doesn't mean it will be any cleaner now does it?
