I'M FLYING TO GREECE SUNDAY - ADVICE?

This is what I've received so far:
  1. Bring all of my life savings in cash
    Because they need all. of. it.
  2. "If you see people gathering, run because HAVE YOU SEEN 300?!"
  3. "Don't let them convert you to Zeus or whatever."
    Wait wait wait..you know Greece dropped Zeus like 2,000 years ago, right?
