I recently saw a sign on a corner store in a neighboring town that read:
No shoes
No shirt
No English
NO SERVICE
Could be confusing - sounds like they would serve me as I'm English, but not Americans! :D
Just out of interest, is it a requirement for immigrants to the US to speak English or is the problem with non-English speakers caused by illegal immigrants? In the UK potential immigrants now have to demonstrate their ability to speak the Queen's English and show some understanding of our culture and values.
