Dear German Speakers, don't be rude and disrespectful give foreigners and tourist the chance to learn German by speaking German to them if the foreigners are willing to speak German to you. If you don't give foreigners a chance you are putting your language in risk of language extinctions. Plus Your language is a world language (lingua franca)
