This all reminds me of one of the funniest things I've witnessed in a long time: was doing a service call in a gas station... watched as a Chinese customer got into a shouting match with the brown GSA...
both trying to speak English, both with a thick accent, neither understanding the other AT ALL... best part was, I could make out enough to realize, they were both saying exactly the same thing, they just didn't realize it... so they kept getting louder and louder until the customer stormed out
