I didn't read the whole account but he didn't offend him. He didn't go and yell at him or anything, he was discussing something which he should apparently know since he is of that ethnicity. That guy went out of his way to go to THEIR table REPEATEDLY and resorted to physical violence. If this happened here, the first time you'd be told to get the f... away and mind your own f....ing business. The second time someone will smash a marble ashtray in your nose.

Oh Europe, you and your cultured societies...
