im an audi tech at an audi/vw dealership. in the 'tire room' [tire mounting and balancing equipment, pressure brake bleeder, trans jacks, engine stands and hoists, a/c machines, drill press, bearing press, parts washer etc reside there] we have a mezzine for storage. i carry my bike up and hang it by the saddle[with a rag protecting] from the metal rafters. the other three bike commuters do the same.
