While myself and my partner were travelling through terminal 1 disabled security area 10 my partner was stopped by a male security officer. He took my partners walking stick and started talking in French to her when she didn't understand he got aggressive and said if she is in France she should understand the language. Seeing my partner visibly upset u said to the security guard that he was rude,to which he replied you think your better than me. I replied that I didn't to which he said that I should know French then. This is a disgrace that someone dealing with the public should have this attitude It doesn't reflect well on the French people who up until that point had been lovely.
