Hopefully they will do it right. I'm tired of bike shops (at least the ones around me) that insist on storing all their parts "in back". I would probably spend a heck of a lot more money in my LBS if I could go in and actually browse the parts they have. Half the time I don't even know what I want and I end up buying it online. If you are that worried about shoplifting, store them in glass display cases or something.
Also have some sort of logic to the store layout. Why are tires in one corner of the store, and fenders in the opposite corner of the store? Bah, I'm just ranting. Every time I go to an LBS around me, I end up leaving frustrated.
