>At the end of the day.

...we'll call it a day. But what have we called it before?

>At this moment in time.

"At this point in time" is no better. And they never bother to say "at this moment in space".

>I hear what you say.

But then, I like "you heard me".

I think the crutch-phrases are a good sign. People use them to gain some time to think up the next thing to say, which means that, despite the vast evidence to the contrary, they are thinking while they speak. I predict that a cynic on duty would add "they do think, but not about what to say".
