Lol, gossiping about what the Women talk about

I don't like it when Indian's on the phone do it. They say it to everyone, you know they don't mean it, lol. Seriously, Sir should be reserved for those that actually know you and respect you. If some random squirrel said to me "Excuse me, Sir", i'd probably raise an eyebrow, pause, and ask, what's your name, nutty?

I really don't appreciate false niceties or small talk.
Even if I was the manager of a business, i'd get the employees to call me by my name. (I know about business boundaries and that, yes)

I once called a guy, Sir, on a support forum, years ago, he nearly started having a go at me, lol. Dude was 49, and I was 17. What else was I suppose to say?

Sir, makes me suspicious, slightly offensive, but wouldn't bother me.
