MMA gyms in large Polish cities

Have any of you ever trained at a mma gym in Poland with a large presence of hooligans and ultras. and if so what was your experience like training with them or partnering with them during exercises or sparring? did they try to hurt you or get off making you feel pain? and did they follow instructions well by the instructor or argue with you how you should hold pads etc.?

yES I told them all about your views on poland and showed them a photo plus your address.

In the words of Zibi Boniek: "Gość pier***nięty!".

While in Poland, I used to train with Polish "criminals" / mafia guys (mostly body building exercises). Surprisingly, I had no problems, they were friendly and helpful. Some of them spoke the jail language (grypsera in Polish), but overall they treated me fairly and didn't cause any troubles, even though I was not one of them. Sometimes they tried to sell me some stolen goods, but they weren't angry when I declined.
