Please don’t call me, “Sir”. You aren’t my servant.
“Sir” is so upper class English and Continental. What? ??
If I were to meet you in person would you expect me to address you by your last name without using the title Miss, Mrs. or Mr.? ( As in, “Republic”,please brew my tea! Make sure it is Earl Grey!” )
You provided a study from a less than unbiased source and are now complaining about the cost of this and that.
You are not answering the question(s) I asked. You are wasting a lot of band width ignoring/ avoiding my question.
Further where I come from we address each other as Sir, Ma,am, or Miss as the case may be. That is how I was raised, it is called being polite.
Have a good day Sir.
