I ride to work , but lock my bike up outside. Why would it be ok for me to bring my bike inside, especially after it's wet outside and all the grime is brought in to drip onto the floor? I leave my bike outside when it's wet out of respsect for the landlord, though i do lock it close to the building entrance to keep the rain off of it. Parking a bike in a single office isn't a big deal, but if the bike is in a walkway area it becomes a hazard - not to mention an eyesore (not everyone finds metal tubing, chains, cables and gears as appealing as I do).
If you owned the office space would you feel the same way?
