Do they even record it?
I reckon they just tell you that so you don't do your Block & start swearing at them!

In saying that when I worked for the Government & told some jumped up clerk in Brisbane what I really thought of her job performance they DID have a recording of that.

They made me do a "Code of Conduct' course, they weren't impressed when I told them me doing the course wouldn't make the person in question able to do their job.
