We have the same thing at our work - we keep getting reminders that taking bikes into offices is a fire/earthquake hazard...

I keep taking my bike into my office... it is open plan for 26 staff and we can have up to six bikes parked inside on a good day (2 other members also bike, but they lock their bikes up outside in the grotty bike racks)

I always reply to the emails with an explaination that I would be happy to lock up outside when that lockup is secure and gentle on my steed - no way am I leaving $NZ3500 outside in a nasty metal frame that will bend my front wheel and that can nicked - or that can have the bits nicked off it!
