Oh gee. I've done it. Rather than put more $ into my account, if I have a few bucks left I'll play some supers at tracks like LAD or someplace I think is *easy* that I know well. It's amazing sometimes, you spend 0.10 and get $15 back on your last few cents.
I've actually said aloud "oh gee, I need some money" and then gotten some----- exactly the way you describe.
