Didn't mean to make you think it was technically wrong to have the qr on the right, I do bike assemby in LBS and was always told to put them on the left. Most people mount the bike from the left and it gives you an opportunity to do a quick scan at them before you start to ride. I usually have mine in a certain position so I can see if they have been messed with by doing a quick look.

Had some kids loosen mine once when I went into a sub shop to get a sub, I guess they thought it was funny. So now I just give a quick scan before I ride if I left it parked unattended somewhere. Guess I'm a little paranoid after that experience.
