In recent years, Burger King Denmark has initiated a wide range of improvements to better the customer experience. From made-to-order Whoppers, to fresher ingredients, to new and improved restaurants and of course, a better customer service.

The brief was to change the perception of Burger King’s online customer service and drive new customers to the restaurants to try the Whopper.


Promote Burger Kings online customer service

Increase customer service as a core Burger King attribute

Get McDonalds customers to sample the Whopper

We made a deep sweep of fast food brands social channels to understand past customer interactions and how to improve them in the future, which paved the way for

“The Whopper Reply”.


Burger King took over McDonald's Facebook page.

With a cheeky tone of voice we helped McDonald’s provide some long-lost customer service to more than 1100 neglected Facebook posts. With “The Whopper Reply” we helped McD get back to disgruntled online comments and complaints with more than just an answer; every reply included a voucher for a free flame grilled Whopper that McCustomers could pick up at the nearest BK.

To make each voucher personal, we developed a digital tool that applied the first name of every individual to all the links we shared, thus linking every reply with a personal greeting when people arrived at the voucher page.

This way we created thousands of unique URL's to make the experience even more direct.


To make an impactful message about Burger King's ambition to elevate customer service, we went deep into data gathering in order to find the right approach for a campaign.

Our research proved that burger lovers were left hanging on McDonald’s Denmark’s Facebook page and local restaurant-pages - and discovered that only about 10% of the comments and complaints had been answered.

Neglecting a highly engaged audience on social channels was our opportunity – and our approach was too help. Not just our own customers but McDonald's too, as the target audience is pretty much the same.

We replied to every individual with a free burger, proving our knack for customer service with a clear CTA to sample our hero product, the Whopper.


After months of confidential planning, we gathered a team of 15 copywriters to write as many funny and unique replies as possible over the course of one night to make sure that every online community manager from McDonald's were sleeping and wouldn’t block Burger King’s profile.

We wrote more than 1100 unique responses on McDonald’s Denmark’s Facebook page as well as over 30 local pages stretching more than 8 years back in time.

At 8AM we launched a film about the project that we edited overnight and tagged McDonald’s saying “we’re here for you” as a last comment on the stunt we just pulled and our main piece of evidence that created PR for the activation.

Fans of McD woke up to long-awaited replies on comments they had made – and free Whoppers as a reparation. The reactions were beyond positive.
