There wasn't one when I was a boy in the US, at least not that I remember. I think that they started to be a thing around the time I graduated college, and of course they're now everywhere. Just today I paid for some coffee and got back an integer number of dollars because the clerk made up the cost. Of course, it was in her interest, because I throw change or a dollar into the tip jar when the tab is small enough that the tip is less than a dollar.
