No. A guy from the group managed to de-escalate the situation. As for the "God Bless America" song why do we need to sing it? We are a mixed group from Germany, France and China, half of the group doesn't speak English and the other doesn't know the words.
No, sir, you may not. I'm currently in Canada travelling with a group of people. Several times we heard strangers passing by were mumbling "f**king tourists". We tried to ask the last one what did he just say, he avoided to answer, we told him to shut the f**k up, and after that he attacked us.
