A jeweller participating in an exhibition has two sets of jewellery on display. He puts a price tag on one set as very expensive and exquisite and the other set at market price. The audience were awestruck by the expensive and exquisite jewellery set and did not care too much about the other jewellery set. The next day he switched the tags such that the market priced set become the expensive and exquisite jewellery set and the expensive jewellery set became the market priced jewellery set. The audience coming in were awestruck by the expensive jewellery set and did not care likewise for the market priced jewellery set.
