I have friend who told me that his father speaks broken english to non-native speakers. If they hire landscapers, for example, he'll start mimicking a hispanic accent and dropping words and deliberately changing grammar. His entire family is terribly embarrassed by this behavior, even if he means well. What a tool.

As we've been told since at least the early nineties: if a non-native english speaker can't understand you, just repeat yourself and ASK LOUDER. /s
