Bicycle detail

I brought my bike to Westside Joe's Bikes for a few simple repairs. They took the bike, but I noticed that they never locked it up when it was inside the shop. On Friday, July 21 I called them to see if the repairs on my bike were done, and they said they'd look into it. Then later that day around 7 pm, I received a call from Grae, the owner of the shop, telling me that he believes my bike must have been stolen from his shop when he probably walked into the back to use the restroom or something, and given that he admits that they don't lock the bikes up when they're inside the shop, he says it was stolen from his shop.
