Double Decker bus

Santa Singh and Banta Singh landed up in Bombay. They managed to get
into a double-decker bus. Santa Singh somehow managed to get a bottom
seat, But unfortunate Banta got pushed to the top. After a while when the rush is
over, Santa went upstairs to see friend Banta Singh. He met Banta in a bad
condition clutching the seats in front with both hands, scared to death.
He says, "Are Banta Singh! What the heck's goin' on? Why are you so scared?

I was enjoying my ride down there ? 

Scared Banta replies. "Yeah, but you've got a *driver.*"
