Ariake Arena

OK, I understand that money rule the world, but are 100 T-shirts, sold after the concert, worth the 30 minute suffering of thousands of people who already paid you for the concert? What they did is epic. They forward the entire crowd after the concert through a SINGLE exit, so that all the people pass near the merchandise. And the table with merchandise occupy half of the passage width, which (probably to a big surprise of the arena managers, or was it intentional again?) caused an epic traffic jam. After the merchandise tables the crowd moves freely. Put the merchandise outside, as they normally do in Nippon Budokan, or put it out of the people's way, at least. I never had a problem going out of a concert venue before. This is NOT SAFE AT ALL, what happens in case of panic or disaster? They will not have time to open the exits. All exits must be opened, safety must be the first priority, not money. I wonder, if they have passed a real safety inspection? Another point, how about some extra ventilation? My wife almost fainted even during the concert. Just press the ventilation button, now!
