Same happened to my friend. He worked a summer job for a new bike. Buys it. We literally ride it to Walmart to get a lock for it. Park it inside the garden center so nobody notices it. As soon as we're in the door, another group of kids walk up to the worker and tell him we stole the bike. Worker gives the kids the bike. They leave. A few minutes later in the store, we're approached by security and questioned.

The Police found the bike a few weeks later. Stripped down and repainted. Totally thrashed. Good times growing up.
