For me, taking the bike inside the workplace is a no-no. I work in a hospital and the infection control team would have a bird if they saw me wheeling my bike through the halls (not that what I track in on the soles of my shoes is any better). If I want to commute to work, I need to lock it up. Believe me, if there was a better solution I'd be all for it. I would love to see some bike lockers, for instance.
