Glecs,
What you witnessed is what Qatar is able to deliver.
After a few major events in Qatar, I have concluded quite a while ago, that I would never step in again in an event of this scale organized in this country.
They can't deliver and some how they mange to buy the Media to self-claim and report "huge success".
It was the same for the 2006 Asian Games. A huge chaos and always reported as a huge success!

This is a country operated by foreigners but led by inexperienced and incompetent locals. The results are what you witnessed yesterday. It has happened on and on and it will continue to happen. Attempt to go to any next big event and experience amazing guaranteed chaos again!
