I'm a manager for a delivery joint with a high sales volume. We get our average number of drunks and jerks a week, but one lady took it too far, as to personally threaten me over something not my fault. A friend reminded me of something we used to do in high school as a prank: tuna fish shoved into the muffler of their car. It supposedly does no harm to the vehicle, hence no vandalism charge. But for about four days the car smells like a fish market at high noon. Anyone know if this DOES do damage to the car and can i get in trouble for it???? The address is on my fridge and tuna in cupboard.
