So why do you use a Chinese restaurant as an example of where people should speak English? They're not talking to you, so why should it concern you what they are talking about? It's their business.

You are trying to backpedal now.

I fail to see how it's disrespectful, either. You should consider getting "TALK TO ME IN FUCKING ENGLISH" tatooed on your forehead, but I don't think your bosses at the private school would like that, and I hear that God abhors body art, particulary the profane kind.
