Only when talking about hispanics. Every Pole, German, Irish, Asian, etc I've known that have been here for more than five years speaks English. I know several hispanics that have been here for decades and I still can't understand them.
You can’t understand them because it’s a scam they play at. A ridiculously silly little scam but it works because then they can claim they didn’t understand that you the edging done when they mowed. Funny how they can make you understand they want full pay though.
