State employees were given free one-day vouchers to the expo, and according to one worker, threatened with wage cuts, in order to fulfill the target of 70 million visitors. Long lines at the Germany pavilion caused visitors to shout "Nazi, Nazi" and attack workers, according to general commissioner for Germany's pavilion Dietmar Schmitz. Free tickets to an expo show featuring K-pop group Super Junior caused a stampede that injured 100 people, which spokespersons for the expo and the Korean pavilion allegedly denied.
