Why are some people like this

Was recently travelling from Bhopal to Indore in the new chartered bus .. really a good experience . As usual Pappu and pappu par halt tha . There was a group of 4 - 5 boys who got down with everyone ...and they were smoking and chitchatting .. suddenly all of them decided to have tea and by this time the bus driver about to blow the horn and call the passengers ... These guys they took their tea and the driver blew the horn ... Aur kya gilaas lekar hi bus mein Chad Gaye ... Imagine the chaiwala ... 5 glasses gone in a blink .. Aisa kar ke kya hi milta hai logo ko .....
