1. When the driver suddenly feels like going fishing instead
2. When the passenger carries hazardous flammable materials, refuses to comply with safety laws, or fails to appear at the pickup point after the waiting timeout period despite multiple contact attempts
3. When the driver notices the passenger is carrying a shopping grocery bag
4. When the driver decides they only want to accept passengers who wear red clothing
