The situation in Greece is so bad that I think they let them go because they fully prepare for a total structural collapse this year. The EU helps don't reach the lower infrastructure and the people.
I fully expect Greece to become a failed state at this point... sidenote: I am watching a travel vlog in German which is truly eye opening, if you think Greece is just having some finance problem you are not even knowing 20% of it. Greece is in a TERRIBLE situation. Hospitals have started using the Triage system. In about another 6 months the situation will become dangerous. By then all those who got fired will lose all financial helps. That means nearly 50% of the people will have no money to spend. And banks don't give out any loans.
At this stage nearly 75% of all economy is down or on the way down. All local businesses are failing. 80% of youths are unemployed, 50% of all wages are on HOLD.
If you think they worry about tourism at this stage.. well let's just say.. things are bad.
