Food prices at Ferihegyi Airport

I was waiting to fly somewhere and as I still had plenty of time, I bought a soda that was three times the normal price, sat down and started to read a book. Two American businessmen next to me tried to figure out how the ended up paying what they paid for their food, what cost what, etc. At the end one of them said, "I think the prices are deliberately vague."

Of course, I know this but having heard it put like this felt like overhearing a true bit of wisdom.
