Yes I was in a bit of a hurry. There was about a minute to go before the race. Even so, I still should have made absolutely sure that I was putting on the bets that I wanted to put on.

Betting on the internet is good in many ways but this is one way where it's definitely not. I've been writing out TAB tickets for years, so I wouldn't have made this mistake at the TAB, but if I had, when the lady said "That's $90", I would have been able to ask her to cancel the bets for me. Instead, on the internet, once you've confirmed your bet, that's it. And today, I didn't actually know about my mistake until a while after the race when I noticed that my balance was about $50 lower.
