Faking allergies, trying to create your own dish and expecting to be catered to at a moments notice: these are the things driving Kiwi restaurateurs wild.
Restaurant Hub Founder and former award-winning chef, Mark Gregory, told NZ Herald, "We call them "mixe-matarians".
"If you're not allergic, for God's sake! Do you go into a shop and say, 'I love that cardigan, but do you have it in yellow?'
"So why come into a restaurant and say, 'I love that but can I have the broccoli from that dish and can I have the sauce from that dish. Oh and by the way, I don't eat squid, can I have something else with it?"
It turns out Kiwi chefs and restaurant staff aren't alone in their complaints. Employees from across the foodservice industry have taken to Twitter to share their gripes about the most annoying and infuriating customer habits they face in their jobs.
In what's now become a viral thread, service staff and restaurateurs have complained about the shockingly rude, demanding, and dim-witted behaviour of diners.
The stories, which come mostly from American Twitter users, serve to show just how hard some of these waiters have to work to earn their tips.
The thread kicked off on September 12 when Twitter user @ghetto004 tweeted his appreciation for people in the food industry, whom he indicated don't get enough credit.
"Ppl that work in food are braver than the marines, I SALUTE you," he wrote in an exaggerated tweet. "Retail is hell but food…now that's hell x100. I could never, I'd choke somebody."
Quite a few people agreed, especially after he made it clearer that his comparison to the Marines was a joke.
"Being a waitress was my worst job to this day," a woman named Nida answered, quoting his tweet. "This one b**** complained about a milkshake that 'wasn't made correctly' so I transferred the same milkshake into a different cup with a new straw and she said it was 'much better.'"
Her comment has been liked nearly half a million times, and earned 1,000 comments — including hundreds more stories from other waiters and hostesses.
"One of my favorite things about my job is customers asking if we sell wings... i work at wingstop," wrote @bdlsc_ incredulously.
"I use to work at Cheddars & someone literally called and asked how much it was to eat... not to eat anything specific, just to generally eat..." wrote @KayAngellle_. "We are not a buffet ma'am. I couldn't help but chuckle on the phone."
Another woman tacked on to that, tweeting: "Omg ppl used to do this all the time when i was a host & when i didn't have a straight answer they'd hit me with a 'you really can't give me an AVERAGE price?'...like girl the menu is literally online. if you want the mean, median, and mode of the prices def feel free to do it yourself."
Then there are customers who seem to complain just for the sake of complaining — as evidenced by the way waiters can so easily fix the problem without doing anything.
Twitter user @cestdarko complained, "One time had a customer that kept complaining that his milkshake was too thick & we ended up having to put just milk with flavoring & he was like "finally, why couldn't you make it like this in the first place."'
And @ElenaWhiteley added: "Yesterday a woman ordered a diet pepsi and i poured it myself so i know it was diet and when i brought it over she said 'this is regular pepsi, its too sweet' so i went and got her another diet pepsi and suddenly it was fine i dont understand."
"Had a guy once tell me the salad tasted like the greens came straight from the bag. I told him 'yeah our garden isn't working today'" tweeted @CervanteZyd, who added that he got in trouble for the snarky comment.
"Working at chili's i had a lady tell me her pickles were too much like cucumbers," griped a woman named Miranda.
A few people complained about finicky older customers who seem hell-bent on making things as difficult as possible.
"Old people aren't satisfied with their experience unless they've complained at least 65 times and sent their food back twice that amount," one person complained.
"Had an old lady complain one time that her food came out too fast and she wasn't ready for it," recalled @jakelon8. "SO SHE DEADASS SENT IT BACK AND WE HAD TO MAKE A NEW ONE 15MINS LATER."
Twitter user @___teraa97 remembered a woman who said she had a dairy allergy, so she didn't want coconut milk in her soup. Coconut milk is made from coconuts and is non-dairy.
