Most of us have gone for booking a Marriage Hall for Bro/Sis.. relative or own wedding..
There they have this monopoly system of Decorators and Food Providers.. SO you have to pay the Price they quote even though you know... by Cost it should not be that high.. and you also know even if u add a suitable margin it should not be that high.. but the margin for them is huge.. as they sert the prices.. and there is no one to challenge it.... since it is a monopoly. Same with the Builders Union.. or Cartel.. Their Costs are not hight still they want to sell it for huge margins...!!!!
