Let's face it - it happens to everyone. You think you've packed your chargers and it turns out that you haven't. And neither has your partner. Nor anyone else you're travelling with. Dammit!
If this ever happens to you, see if you can drop by an electronics shop like Harvey Norman's. If you're lucky you might be able to buy a new battery or charger for your camera and be done with it.
Alternatively, if you can't or don't want to buy a new battery or charger for your camera, what you might be able to do is leave your battery with one of their sales people. Turns out that shops like these often need to charge camera batteries themselves (I guess they need to keep all those display cameras nicely charged, don't they??) and so they have a universal charger which they may just let you use for an hour or two while you wonder around and grab a cup of coffee.
