Bicycle detail

I put the bike right next to the entrance door in view from the inside. I stepped into the store to order a smoothie, as I'm ordering I'm monitoring my bike and i turn my head while placing the order and the bike was gone. I went outside to see if the thief was riding down the street in either direction but nothing. And one of the customers sitting outside said he didn't see it happen either. I immediately let the store associate know and they called the owner to check camera footage.
