No worries, mate! :)

Yeah - having to add up prices in the States for everything (tax + tip) was a nightmare. You guys are used to it, but for me (and my wife) it just seemed like a crazy, crazy system. You'd walk into a shop, and the price tag on the item was never anything like what they'd ask you for it at the counter.

Shame you didn't like vegemite. I suspect, like tipping, that if you're brought up on it it's much less distasteful. :)
