Paid a high price as a student

for the ~400€ i paid, i must say that the "Lunch" was outrageous! Plus i`m a human being - i need fluid to life - those crappy water cans ain`t enough!

Another thing - there were that many people without the correct passes joining the keynotes and session - why have i paid that much money when other people only purchased the very cheap tickets an got the same things?
