Onena,
Not psycho, perhaps just ill-prepared.

next time: go to the airline website, simulate the issue of your ticket, choose their best offer (varies with dates and ticket class), verify all the ticket conditions and restrictions and once you are sure that you have the best deal that suits you, press "purchase ticket".

please be reminded that even when you have done your hard work of making sure you have the best offer, and your ticket is issued, nothing guarantees you that the next day, you won't find a promotion of a kit kat chocolate, that offers you a 1st class ticket around the world if you buy 1 kit kat.
This is marketing and the world we live in, today!
