and those from Uzbekistan are used to behave like some little oriental despots in addition - oh, you may not criticise them!

Do you harbour some enmity towards these central asian people because they were very pro soviet? Estonia was also a republic of the USSR if I am not mistaken. I cannot for the life of me see what uzbek people have to do with this, most training centres follow the crappy swiss model aka EF, so not really fair to lay the blame at any one nation or peoples door.
