I deliver at the Jimmy John's in Wicker Park. I took a delivery on foot because it was so close and when I returned my bike was gone. I'm sure that it was taken through the back door because this door was ajar when I found the bike gone. Because it was take through the back, I'm led to believe that the thief was somewhat familiar with the store. Also, had it been taken through the front door, my coworkers would have seen it happen. My boss made a point to mention that he didn't remember any customers enter the store after I had taken that delivery on foot which means that it was most likely stolen by a customer who was already in the store when I left. Tomorrow I will be able to see the surveillance tapes of it happening and it seems pretty likely that I could recognize the thief as a costomer if nothing else..
