Bob said something to a coworker John that although was not offensive, made John mad at their retail store job. John decides to go slash Bob's bike tires. The next day, while Bob was off work, John brags and tells everyone what he did. When Bob get to work the following day, John comes in and quits and admits to the manager what he did. The manager calls Bob in, tells him not to be upset, but tells him that John slashed his tires and he quit. John is friends with the manager and he continues to allow John to visit the store frequently although he is not buying or has bought anything as a customer, visiting every day since he has quit to sit and have conversations with both the manager and coworkers. Bob is concerned that if John was willing to slash his bike tires, would he be willing to escalate his actions to anything further as he continues to visit the store with no purposes of shopping. Bob voices his concerns to management but they say we can't prevent John from coming into the store and advises him that he should file a restraining order. Their policy stated that because it was personal property, the company is not responsible for he property that was damaged.
