What to do if someone puts a Snickers in your gas tank?

If someone puts a Snickers in your gas tank, do not start the engine, as this can cause further damage. Safely remove the fuel cap and assess the situation, but avoid reaching in directly. Contact a professional mechanic or towing service to properly drain the tank and inspect for any potential damage before attempting to drive the vehicle. It's also a good idea to report the incident to the authorities, as it may be considered vandalism.
