Not in Perm. Ever been to Russia? Let me tell you about buildings in Russia someday.....
Nope, never been to Russia, but even the biggest nightclubs are still small buildings and have too little space and ceiling heighth to allow fireworks to always fizzle out without landing on something.
There have been several terrible, mass casualty nightclub fires in the US. I remember one in Kentucky twenty or more years ago. Fireworks in a nightclub just insane.

Not fireworks in that Kentucky fire, but small buildings with large numbers of people are the last place fireworks or any obvious potential fire hazard should be allowed.
