When you buy something, do you give exact change?

When you buy something, do you give exact change?

That is if you're using cash. I personally don't, even though I probably should. I don't want to go through the trouble of finding change and it takes a while to find it.

By exact change I mean if something costs $20.30 for example then do you give the $0.30 to the cashier? I just wanted to clarify that in case someone doesn't know what I meant.
