Lets say they carried 10m passengers last year (and we all know it's more).
And lets say RYR charged each and every one of those passengers an extra 30cents because they
"had no change for the coffee".
That's a tidy 3,000,000euro for doing............er nothing !
(edited for clarity - slip of the tongue - again)
Like the man said. While they run the scam, they will carry on running.
