I have never, ever heard someone saying they forgot their card in the handfuls of European countries where I have been. I have heard complaints about the ATM "eating" the card (not restituting it; this happens sometimes for various reasons). You'd have to try very hard to do it (like take the card out, because otherwise you won't get any cash, and then sticking it back in, or just leaving without taking either cash or card). This just is not a problem.
