Query: Zip up completely!

It has happened several times in my room before I entirely dropped my camera and lenses out of my bag on the concrete driveway last Saturday. Without knowing that your bag is not zipped up completely and if you lift your bag up, it spills your camera and others out of your bag in a split seconds. This morning, I paid $570 to repair my 5D II and two L-lenses at Canon Service Center. What can I say...I HATE the bag! :-)Update: Canon Service Center re-estimated the repair service charge. Now the final charge is $981 !!! A cheap Canon bag takes that money out of my pocket for its mother company. :-(
