That’s not how it’s meant. It’s like “my bad” or “oops”, not “please don’t get mad at me and tell mommy”.

It’s simply a token of speech that expresses acknowledgement that there has been a misunderstanding.

What makes this so irritating is actually the fact that you subconciously know that it was your fault because it was your bad input that lead to the bad output. People have a harder time forgiving when they are in the wrong than when they are in the right because of cognitive dissonance.
