Lost property and secret recordings

I picked up 3 young women tonight in their mid twenty's they wanted to go from Trigg to Cottesloe. Anyway after about 10 minutes 1 of them asks me for my cab number and promptly sms's it off to a friend. I thought that was a bit strange but she says she has a habit of leaving stuff in cabs and wanted to make sure she knew the cab she had been in so getting her stuff back would be easier. I suggested just checking the cab when she got out would be the smart option but it seems she is a serial loser of stuff in cabs. The tally was 8 mobile phones, 3 handbags, numerous sets of keys and sunglasses.

Anyway towards the end of the fare she says "Shit!, I've been video recording the whole cab ride since we left home. Everything we've said has been recorded and I've just sent it off to 'Beck" Now I'm not sure how to feel about this. I mean had she not sent it too her friend I would have asked her to delete it as I wasn't aware I was being recorded and didn't feel too comfortable about it.
Am I overreacting?? Conversations happen in taxis that would be inappropriate in another context but from what I can remember nothing was said that I should worry about.

What do yo think?? If your a cabbie how do you think you would feel being taped without your permission? I'd never even thought about it but with mobiles today it's certainly possible.
