It is not uncommon in India to buy attendees for Political rallies to demonstrate strength of support in the public. And it is quite common to buy film stars to attend major functions to add some glamour to the evening. But have you ever heard of buying some guests to appear in a marriage?
I Came across a news story(Entrepreneur cashes in on rented revellers, http://www.freelanceuk.com/news/1311.shtml) talking about a booming business of "arranging" guests for marriages in India. The enterprise, called "The Best Guests Centre" in Jodhpur, Rajasthan, India supply guests in the required traditional attire to the ocassion for a charge. The madeup guests do everything they can do to make sure that the ocassion is celebrated in the true(?) spirit.
What else you can buy for your marriage? Hell no. Don't say, bride.
