re: Sir and Ma'am..... Do you use it?

I'll teach my kids to use sir and ma'am. Once you reach a certain age though, it's not really appropriate or needed. I can understand addressing an elderly person this way, but honestly, most people these days are insulted if you address them this way because they see it as you acknowledging that they are old, even though the intention is to show respect.

I'd never address someone in the workplace this way. I would be laughed at.
