From AdamK: "Regarding a different type of implicit consent, you consent to all terms in the Contract of Carriage and applicable fare rules/tariffs when you purchase the tickets. This is applicable to cancellation fees, overbooking procedures, and things like the statement where you agree to have your belongings searched at any time with or without your knowledge and you agree to your person being searched. If you don't agree with all the terms in the Contract of Carriage, you should not purchase the ticket."

Then you don't get it either, do you?

Never doubt that a small group of thoughtful, committed citizens can change
the world. Indeed, it is the only thing that ever has. -- Margaret Meade
