Just wait a generation before we freakout. After the influx of Chinese from the mainland dies down and they've been here for a generation all the signs will be in English and their kids will have orange hair, baggy pants, ride the Skytrain to Metro Town and be called Bob. Then we'll have moved on to some other stupid immigrant crusade.
Like stopping East Indians from driving dump trucks.

This is much ado about nothing and if they want to lose business because of their language prefernces let them because an idiot in any language is still and idiot.
