But if she was just playing, why place coins in the machine?

[I still care]

I'm just guessing of course, but it doesn't say she placed coins in it. Sometimes machines have coins in them already, and you don't realize it.

Just last week I went to the stamp machine in the PO, and someone had walked off leaving almost a dollar in change in the machine. It was waiting for the next order, and when I put in my order for 2 stamps, I got them for free.

I've never experienced that in a washer in a laundromat, but there is often leftover times in dryers. In any case, this woman is in a boatload of trouble. Even if don't mean them to go, those washers look airtight, pretty scary.
