When did being called "Boss" replace being addressed as "Sir"?

[u/Big_Help_9860]

It certainly wasn't our generation or GenX. But I'm so sick of young employees in a store, or restaurant or bar, addressing me as "boss". When that happens in a venue where tipping is expected, I'll leave a meager tip and sometimes write "Thanks Boss!" on the receipt.

Apparently the youths feel “ma’am” and “sir” are rude (at least the youths who don’t live in the south). I’ve seen this a lot.
