The theater does not allow access to people wearing shorts, not even in the Gallery. Although it has remained one of the last theaters to apply such formalities (unlike Opera in Paris, Royal Opera House in London, Met in New York ...), I recognize that it was my mistake, as the rule is well described on the site .
After changing and taking a seat in the Gallery, I notice that many girls are wearing shorts or shorts, much shorter than those I wear.
The inability to enter wearing the aforementioned clothing, as the site punctually reports, refers to spectators, without specifying their sex.
This treatment is trivially discriminatory.
Compliments.
