“For a free ticket, you agree to wear a swastika symbol in the auditorium,” Theater Konstanz wrote on its website. A “regular purchase” gave patrons a Star of David and represented a “sign of solidarity with the victims of National Socialist tyranny.” The symbols were being offered just before the performance as a sort of social experiment.

As part of his 11 euro admission (about $13.50 U.S.), Schuster was handed a Star of David. The 33-year-old said he quickly put the Jewish symbol into his pocket because he didn’t want to make any type of statement by wearing it.

While more than half of the theater’s patrons did not wear a sign, he estimated that about 30 people chose to wear the swastika.
