Barbara,
I'm so sorry to hear that news. It's a sign of the times in Canada. I cannot believe the crime rate increase over the last nine years we've been summering in Vancouver. Used to be we never saw any violent crime news in the paper, and now it's as regular a feature as it is here in the US. Crime in Vancouver has escalated dramatically. There are pretty obvious reasons why, but it's not a politically correct topic for discussion here. I guess the Olympics will bring out both the best and the worst of Vancouver. It's a shame you had to be victimized. It's not anything I would have expected, either. But I know that's little consolation.
I'm surprised you cannot get your money back. Surely the police can arrest the party involved and perhaps recover your loss.
I hope this event won't spoil your vacation. Enjoy the Olympics!
