Nahji Chu, the owner of popular Vietnamese restaurant Lady Chu in Potts Point, in Sydney’s inner-city, put through an order of profanity-laced fortune cookies for Valentine’s Day.

She was shocked and slightly tickled to receive a response from her manufacturer who said they were no longer accepting “offensive” language after her messages were mistakenly mixed into other customer orders.

“I said, ‘This is a personal attack, and you’re discriminating against my messages’,” Chu told 9news.com.au.

“It’s for my customers, within the context of me and my brand… If you’re getting it mixed up with other restaurants, that’s not my [fault].”

In an email, the manufacturer said their other customers were “quite upset” to find Chu’s messages inside their custom cookies at the end of last year.

“As a result, management have decided to no longer accept customised orders with offensive or expletive words,” the email read.

Chu was told she could order empty cookies from her supplier and insert the funny messages herself.

She hit back at the manufacturer in an email after her joke fortunes were rejected.

“I don’t see why this is my problem. My orders are private and is my IP and if your factory gets it mixed up with other people’s orders, then this is your error, not mine,” she said.

“My messages are private and are for my clientele and are within our context. They all get my humour.”

Some of Chu’s fortune messages include, “The year of the Snake bears good fortune! Your divorce is coming soon” and “I only married you for your money you ugly c—.”

Chu said her Valentine’s Day order was not fulfilled and she’s been stuck inserting the messages into the cookies herself ahead of February 14.

It’s labour-intensive work, but she wants her customers to enjoy her cheeky signature messages.

Despite complaining, Chu said she was firmly told her orders can no longer contain offensive language or profanities.

She won’t go to another supplier, with the manufacturer the best value for her restaurant.

“Last year, I spent close to $10,000 with them,” she added.

For now, Chu is happy to chalk it up to a funny Curb Your Enthusiasm-style moment.

“I’m gonna just take out the profanities and be creative,” Chu said.

“They’ll still be funny and rude… just no swear words.”
