If I can't take the bike in with me then I don't ride it. I don't trust locks or people. I have taken my bike in Office Depot, Wal-Mart, Albertsons, Target, Home Depot (work), Sams Club, ect... Sometimes I get funny looks and I just tell them, before they say anthing, I never leave home with out it. They just laugh and that's that. Lock are for just keeping honest people honest.
