Most of us are guilty of Al Desko office dining, but according to new research, there's lunchtime etiquette that all workers should abide by.
We've all been in the situation when a colleague has brought a stinky fish dish to their desk for lunch, or someone near you chews or slurps loudy and makes a mess.
While you may feel you need to suffer in silence, you're not the only one who feels this way.
According to Deliveroo for Business, over a quarter of office workers find smelly meals the most irritating when it comes to lunch time, with loud chewers coming in at a close second.
When it comes to stinky foods, 36 per cent of office workers say that sardines are the worst food a colleague can consume at their desk, followed by reheated fish, tuna and street meat. In fact, over a third of workers request that these foods should be completely banned from the workplace all together.
And, it's the younger generations that feel most strongly about this.
A whopping 90 per cent of Gen Z believe that office lunch etiquette is important, followed by 88 per cent of Millenials - taking out the national average of 86 per cent who think Al Desko diners should have better manners.
And it's not just certain foods that are irritating office workers. There are 'types' of lunch time eaters whose annoying habits have made quite the stir.
42 per cent of Tasmanian's find 'The Fad Dieters' the most irritating people to be around at lunch time: people who discuss their latest diet and the foods they must eat and can't eat. 30 per cent of WA also feels strongly about this, with 29 per cent of Queensland also agreeing.
25 per cent of have ranked 'The Loud Chewer,' who is also a close relative to the noisy coffee slurper, at a high level of rudeness, with their uneccessary noises causing a divide amongst workers.
And, of course, there's the typical seagull diner, who's never happy with their own lunch options and eyes off everyone else's lunch options, often asking to have a bit of theirs.
While we all know a few people who fit into these categories, which one gets you the most?
