Customer surprises chef in viral burger video

The customer sounded angry at first

Two men took it upon themselves to praise the fast-food cooks who made them their burgers in what has now become a viral video - after first calling attention to the cooks.

Marcus Jeffers and his friend were dining at a Shake Shack restaurant in Marlton, NJ when Jeffers stood up in the crowded restaurant and demanded to know who made his burger.

“Yo, who made this burger, man?” Jeffers can be heard yelling, before repeating his question twice more in an accusing tone.

As the man working behind the counter scrambles to identify the chefs who made Jeffers burger, Jeffers states: “I know y’all hear me!”

Finally, the chefs are identified as Jason and Mike - at which point Jeffers does something surprising.

Rather than criticise the chefs, as many likely thought he was about to do, Jeffers says: “Jason, you killin’ it, man. Mike too!”

The video ends with the restaurant erupting in cheers and has since been viewed over 11,000 times on Instagram.

And on Twitter, where the video has been shared close to 200,000 times, many are commending Jeffers for the act of kindness.

“This is the type of aggressive positivity I like to see,” tweeted one person.

The video also received the attention and approval of Shake Shack, which tweeted in response: “On point is what we aim for.”

Of his inspiration for the video, Jeffers told Fox News: “We had seen a video similar to that before, but the people that were in it threw the food at the employees, so we wanted to put a positive spin on it and make it our own," and that this was his very first Shake Shack burger.
