Only in Russia.

Here is a sign that can be posted only in Russia.

Found at the entrance to Moscow's "Sea World":

Employees of FSB (National Security Service), MVD (Ministry of Internal Affairs), UVD (Internal Affairs Administration), GUVD (Chief Internal Affairs Administration), <+ 2 other agencies>  and other law enforcement agencies, as well as public servants (officials) of all levels, get in like everybody else (i.e. using tickets)
