Sir or madam or otherwise, that is not how words work.
I once saw a garden center with the french word “soleil” (pronounced “so-lay”) in the name, everyone in the area pronounced it “so-leel”, but just because the French don’t kick down the doors and correct people doesn’t make “so-leel” any less incorrect. There is a correct and an incorrect way to say words, frequency of usage is irrelevant.
