Randomness

The other day I was waiting for bus at the stop... The vehicles were stranded as it was sorta rush hour and traffic jam was at its peak... There was this car stranded right before me and i noticed that a pool of petrol had formed beneath it.. I guessed that the fuel tank was leaking... I thought about it for some time and decided to let the guy know that his tank was leaking... 

Me: taps on the car window and motions to roll down
Car fella: Yes??
Me: I think your fuel tank is leaking.. There is a fuel puddle beneath your car.
Car fella: Gets down and checks the fuel tank, looks at me and shouts "Why the hell are you staring at my vehicle"
Me: What the??!!
