Bicycle detail

My bike was left locked with a cable lock outside a McDonald’s, I went in for no more than 30 seconds to buy some burgers for the homeless around the area, I kept my eye glued to my bike through the window up until I went to pay, I looked back after payment and my bike was gone. I ran out the door and looked in every direction that it could have possibly gone and it was nowhere to be seen. The McDonald’s manager said that there aren’t any cameras facing the front entrance or where my bike was otherwise left, and after asking everyone else in the parking lot who may have witnessed it, it was concluded that my bike was gone.
