You no speak English good
Everyone’s heard of how Grammar Nazis and how annoying they are. We get it, you hate it when others can’t communicate in English very well, but are you really going to let that ruin your day? You will? Alright, then, there’s nothing more to discuss.
However, if you’re going to preach about speaking in English properly, make sure you don’t make an error, or others will pile up on you. This woman tweeted that to her personally, poor English is a turn-off. Unfortunately for her, she said it in a way that that one would consider “poor English.” Next time, maybe keep your mouth shut, eh?
