If you lived in Cajun Country or Barcelona, it would be advantageous to speak like the locals. Proper American English is not proper in the UK. The spelling and grammar in your own comment are improper in either country. Proper nouns, like Cajun and Catalonian should be capitalized (and yes, those were used as nouns referring to the respective languages, not adjectives; though they should be capitalized in either case). Your use of 'minimal' is incorrect. You may mean marginal. I could go on, in standard English or Pidgin. Now please, go home and cook rice. Brah.
