A fast food fan has taken to TikTok to show an "underrated" hack that can get you a free Whopper at Burger King. However, there is a task for customers to complete before they can

be united with their burger. TikTok page @healthyjunkfood shares food hacks and reviews with an audience of 1.1M followers. In the hack, he explained why keeping a hold of your receipt is

crucial. He said: "Get a free Whopper at Burger King with this underrated food hack. Make sure to ask for the receipt. "The receipt will always come with some awesome, incredible

coupon on the back, such as this one which says free whopper. And look at the back, with a simple survey you can get not ripped off." The hack works both at US restaurants and UK

restaurants, although the terms and conditions may differ between the two countries. READ MORE: CHEF SHARES 'NEW FAVOURITE METHOD TO CUT AND PEEL AN AVOCADO' Burger King explained

that the restaurant is also offering a spooky opportunity for customers in honour of Halloween. They explained: "Burger King UK is giving Halloween fanatics nationwide the chance to bag

an iconic Whopper totally free - but only if they dare." However, customers will need to download the Burger King app onto their mobile devices to be in with a chance. "Available

now until November 2, fans can use the ‘Home of Ghosts’ feature on the Burger King® app to scan their surroundings and detect supernatural activity," said the Burger King spokesperson.

"Burger lovers who find a ghost will automatically receive a buy-one-get-one-free coupon to use on a flame-grilled Whopper or Plant-based Whopper, meaning they can grab one for

themselves and get one for their ghoulish friend free of charge." WHAT IS IN A BURGER KING WHOPPER? Burger King now offers both its original Whopper and a plant-based version. The

original Whopper contains a flame-grilled beef patty, topped with tomatoes, fresh-cut lettuce, mayo, pickles, a swirl of ketchup, and sliced onions on a soft sesame seed bun. The Plant-Based

Whopper, on the other hand, is made up of a flame-grilled, soy-based patty, topped with tomatoes, fresh-cut lettuce, vegan mayo, pickles, a swirl of ketchup, and sliced onions all housed

inside a soft sesame seed bun. For those who want to take things to the next level, Burger King also offers a Double whopper, made of two flame-grilled beef patties. However, the double

Whopper is not included in a free Whopper promotion.
