Currency switch

I have a very strange issue. I currently have two currencies for my store – AUD and USD. I’m based in Australia. I had one customer who switched the currency to USD and made a purchase in what I believe was that currency. However, when the order came through on the backend, it showed he had paid in AUD for the amount of the USD rate.

In other words, the item is listed at AUD20 which converted to USD13.05 at the time. However, the backend showed he paid AUD13.05 …

What went wrong?
