Sardars in Mumbai

Question

Two sardars  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 was 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, "Arre 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."
