I think the photo of him at the convenience store either looks like him entering after pumping the gas to pay and perhaps ask directions with a map in his hands OR he's walking back outside and doing what so many of us naturally do - opening the door walking backwards using his back body/shoulder to then turn to face out once outside. I always do this when exiting a place with something in my hand, especially if I'm saying goodbye to someone who just helped/served me. Security cameras are generally always placed *inside* gas kiosks because armed robberies are not uncommon in them. One outside doesn't really make sense to me, especially with the angle shown.
My two cents after studying the photo pretty extensively, closing my eyes, and walking myself through that door. MOO.
