If you don't enjoy the experience, vote with your feet. However, it seems there are millions who do!
No, there are millions (80m. a year apparently) who travel with FR because they are dirt cheap (pun intended) and offer service over routes not served by other carriers. That does not mean by any stretch of the imagination that 80 million people a year enjoy it, that would be like saying a million drivers a day enjoy the M25.
Sorry, but you click the button to say you agree to the T's and C's... If you can't be bothered to read them before clicking, or ignore what it says then I'm sorry to say that it's a fair cop.
In theory I agree with you. In practice, when FR extorted £160 from an elderly couple who had printed their boarding passes, but had then folded them across the bar code rendering them, according to the check in person, illegible, then that's not a fair cop.
