I've looked at the bike rack at my local supermarket and don't feel my bike (or at least parts of the bike) would be there when I came out of the store.

How do you keep the rear rack, panniers, head lights, pump, etc. from being ripped off while shopping since these things can't be locked?
I don't want to have to ride a "stripped-down" bike to do 10 minutes worth of shopping.

Does anyone here feel the same way I do about riding to the store for a few items?
