I used to go bagless all the time, but with the advent of the metal detectors, I find it's easier to have a small bag that holds my wallet, phone, and hand wipes, so I can just place the bag in the bin instead of having to unload pockets and maybe drop the phone. I have the Dooney Haunted Mansion pouchette crossbody bag, that is the perfect size to carry just what I need and nothing more.
