Now most couples ask for money towards their honeymoon or their lives together, leaving us all the awkward position of trying to decide how much to give.
But one bride was completely shocked when her husband's uncle messaged her months after the wedding to ask for a large chunk of his generous cash present back, reports the Sun .
Sharing the story on Facebook, she wrote: "After my wedding my husband and I opened gifts and cards.
"I opened a card from my husband's aunt and uncle and they had written us a £160 cheque.
"We were like 'whoa, but okay he makes good money'.
"Three months later we get a phone call and the 'generous' uncle said he only meant to write a £16 cheque and we need to give him £144 back. Like who does that?!"
In the post she makes it clear they don't believe the uncle has money problem and says her new mother-in-law, who is the uncle's sister, is also furious.
They were so angry they ended up sending them all of the money back.
Her story is the latest in a long line of bizarre wedding tales, and last week we heard about a bride who is debating not serving food at her all-day wedding in a bid to cut costs.
One of her bridesmaids shared her pal's plan on Facebook as she's worried about all the guests being hungry.
She's also concerned guests will be extremely drunk if they are drinking all day without having anything to eat.
The friend wrote: "Okay so, I'm bridesmaid in a wedding in May.
"This girl I've known for about 10 years now is the bride, and they are really focused on their wedding being a nice and relaxed time on some large outdoor property. Lots of handmade items, barn style, bonfire, it's gonna be super cute.
"I love simplicity and it's totally them."
Sounds lovely so far...
She goes on: "I just found out that to cut costs, they're not providing food. Like, what!
"It's a whole day thing, even into the night, and no food?!
"I'm gonna end up ordering a pizza or something for myself, my partner and our friends while we're there I guess.
"Everyone else I can see getting hammered with no food and it's going to be messy.
"As a bridesmaid, should I say something?"
Do you think it's a good idea?
