Having spent 18+ years without a car, walking or cycling or taking the bus, I always had a backpack with me. I would often tell a clerk I didn't need a bag and I'd be ignored -- they just automatically put items in a bag. Once a 5 cent bag fee went into effect and they had to ask, I never had a problem not getting a bag. (To be fair, other places knew me and knew I didn't need a bag.)
