A frozen custard and burger chain based in the United States has sparked controversy with their customers after changing from Pepsi to Coca-Cola products across all their restaurants.
The restaurant chain, which was founded in Sauk City, Wisconsin in 1984, has had a long association with Pepsi, serving their products for many years.
However, some of the Pepsi's favourite drinks, including Mountain Dew, Sierra Mist and Tropicana, have been shelved in favour of Coca-Cola products.
Last week, Culver's made the announcement of the changeover, saying: "This is in progress and will take time as our nearly 900 restaurants located in 26 states make the switch."
The change in produce upset fans of the franchise, particularly in the Midwest where the chain is popular, which has already been reflected on Culver's website.
Customers voiced their concerns on Culver's Facebook page with many replying to the restaurant chain's posts. One person wrote: "Culvers also no longer has brown mustard available. Not sure why that change had to be made. I won't eat a burger with yellow mustard so I am limited to take out. Pepsi fan here, as well."
Another said: "The only reason we ate with you was because we could get Pepsi products. Guess I don't have a reason anymore."
A third person commented: "I have to say goodbye to Culver's because the change from Pepsi to Coke. We faithfully went there for years and now we won't walk through their doors any more.
"If you should change your mind, then let the world know and we will become faithful customers again."
Others celebrated the change, with one user writing: "So happy to hear that you're switching to Coke, cuz I think pepsi is way too sweet tasting! Love coca-cola!!!"
Another added: "Wooohooooooo for Coke!!!!", while a third person said: "Love that you're switching to Coke products!"
Culver's is mostly recognised for its ButterBurger - a toasted, buttered bun sandwiching a beef burger that is "never frozen".
The restaurant chain is not the only company to come under fire after M&M announced it will stop using its colourful mascots after a furious backlash to an attempt at a more inclusive branding strategy.
The company will swap mascots in different outfits and looks for actor Maya Rudolph as she is someone "America can agree on".
The multi-coloured button-shaped chocolates were the object of criticism from right-wing media including Fox News after the company announced a new campaign.
The campaign named "Flip the Status Quo", raised money to support women in creative industries and featured limited-edition candy bags with the three female "spokescandies".
