Fast food restaurants are tightly controlled operations full of rules and regulations designed to keep customers happy.
But some employees can slip through even the most stringent vetting processes.
We surveyed news stories to find the worst fast food workers of the year.
Some employees took gross photos on the job, while others were accused of harassing customers.
One thing’s for sure — you won’t want these employees making your burger.
The popular fast food franchise declined to disclose the location of the sign when a photo started making rounds on the internet, but told TheBlaze it was posted by a disgruntled employee.

The Subway worker who allegedly threatened a customer who asked for ketchup on his Philly cheesesteak.
'(The customer) wants ketchup on the Philly cheese steak and I have never put -- we don't even have ketchup at Subway -- I've never put ketchup on anybody's sandwich,' Lawrence Ordone, a Subway worker, told local station WFTV.
After that, the customer allegedly 'mouthed off' to Ordone and a confrontation ensued. According to the customer, Ordone yelled at him, blocked the door, and threatened to kill him.
Ordone lost his job.
The picture showed the employee sprawled out on hamburger buns next to a disturbing-looking bucket.
'How many Whopper Juniors do you think I've made?' the tweet said, according to Kotaku. 'See if you can figure out it for yourself.'
The employee received a 'strict reprimand,' according to Burger King.
Taco Bell tracked down and fired the employee after the photo went viral.
In a statement on its website, the company said that the photos were taken during an employee training session and the tacos were not meant to be sold to customers.
'We do not believe these employees harmed, or intended to harm, anyone,' the company said in the release. 'But we deplore the impressions this has caused to our customers, fans, franchisees, and team members.'
The two Subway employees were fired after numerous Instagram photos surfaced showing nauseating acts, including a photo of an employee's genitals on a loaf of sandwich bread and a photo of a bottle allegedly filled with frozen urine.

Police told The San Francisco Chronicle in September that McDonald's manager Felix Gonzalez-Becerra 'donned a hoodie and used a replica handgun to force an employee to open the safe and hand over an undisclosed amount of cash.'

This KFC employee was photographed licking a mound of mashed potatoes at the restaurant. The picture was posted to a local news station's Facebook page and garnered more than 2,000 shares and 700 comments.
The employee was fired, and KFC released a statement saying the photo was taken after the restaurant closed and the food was not served.
The unnamed worker who wrote the letter was 'resigning' from his job at Burger King because he was going to law school.
He said he hated the fast food giant and people who worked there, including 'my fellow employees that cannot speak the language.'
