Two PSK Women enter at a butcher shop in Surabaya.
Woman 1: "We want to buy 2 jumbo sausages."
Guard: "OK ... please, 1 sausage cost US $ 3.5, total US $ 7."
Woman 1 then handed over the money sheets 10 US $ D.
Guard: "Well sorry, our store just opened and no change, what if we give a special offer, with US $ 10 you get 3 jumbo sausage for US $ 10.5."
Woman 1: (after thought) "Well we'll buy 3 sausages for US $ 10.
Woman 2: (confused) "what.., one more sausage would we please?"
