I did watch... the security footage afterwards. It was actually my residential building. It was Saturday, I was out of town, and when I got home, the management kindly informed us that the idiot receptionist did nothing but watch when the kids took the bikes. And when I say kids, I mean KIDS, they were no more than 12! They very obviously did not live there (residents all know where the bikes are because they are VERY visible), so my guess is that the receptionist (a guy, by the way) was actually in on the plan to steal the bikes. Sadly, there has been no action taken.
