Receipt for the purchase of a wife?

Part  One:
My non-native friend wants to marry a young lady that works at a café he owns. We visited the parents and they were seemingly thrilled that someone is interested in their daughter, but made it clear that they were not selling out their daughter, that the suitor only needs to take care of her for them.  

We asked what next and this reasonable list was given: the dowry payable to the girl, the father and mother’s stake, the uncle and aunt’s share, the grandma and granddad’s part, the token of gratitude to the girl’s godparents, payment in lieu of traditional farm duties for the girls family, the customary payment to the presiding Imam at the community mosque.

They also said that the young lady’s two dependent siblings should be given something to start life, and that other payables including cola, refreshments and incidental expenses will be communicated before the traditional wedding - “the fashionable wedding is the business of the couple” they said.

Last evening, my friend called me to his house, computed the initial invoice and I am about to collect a few elders to go and do the payment. However, he insisted that I should bring along a receipt in acknowledgement of the payment made for the purchase of a wife. Now my mind is in a worse shape than the world’s slowest-growing economy – like who the hell gives receipts for these things? Anyway, I'll let y'all posted after this visit.

Part Two:  
Anyways, we’re back folks! It was a short engagement at our prospective in-laws’ and I think we got schooled. We talked about the receipt and suddenly moods changed. The girl’s father went bonkers: “RECEIPT FOR DOWRY? Oh my God, you idiots can’t be serious,” and then he said:

"If you think we’re just giving you a lifelong version of your usual one-night stands then forget it. This is someone who’s going to leave her family to be your companion and to share life with you, to save you from your cheap self, give you lawful satisfaction in bed and a family of your own, to open your heart to kindness and give you an opportunity to leave behind a legacy. 

We’re giving you someone who is going to give you a sense of social and religious fulfillment, create an atmosphere that is healthy and conducive to raise your children in; someone who’s going to nurse and cook for you and your children regardless of a public holiday, makes you proud amongst your peers, and does your household tasks with or without a maid.

Now are you still saying it is expensive to show appreciation to the people who had helped in the evolution of this beautiful, intelligent, tasteful and fulfilling partner that is coming into your home to transform both your physical and emotional life, and it’s not like she’s a woman you don't love or we are asking for money you can’t afford?" – Now I am dumbfounded. I think not only were we schooled, but we got owned! LOL
