Post Malone went undercover at a record store to spread the word about the Bentley he’s giving away with Omaze, an online fundraising platform.

Dressed as a store employee in a white polo, white baseball hat, glasses, and khakis, Malone sets out to help customers. However, the first customer in the video recognizes him immediately, to which he responds, “Oh fuck, you got me already.”

However, it’s clear that most of the customers don't know who he is. Malone talks to other patrons, while trying sell his own vinyl records, though in the most backwards way possible: he tells customers Post Malone “sucks” and is “trash.” He even offers to give a customer half-off his record.

Later in the video, Malone asks an older customer to read back some lyrics Malone wrote, while pretending to be an aspiring rapper. The customer, however, isn’t amused. Another customer gives Malone advice on how to create a rap name. “My friend was telling me like if you put 'Young' in front of the last thing you bought, that could be a thing,” the customer says. Malone replies, “Young Flesh Light. That’s kinda sick.”

At the end of the video, Malone asks a young kid who he’s listening to, and the kid replies Post Malone. He reveals himself and the kid smiles and gives Malone a high-five.

Donations to the campaign benefit Folds of Honor, a nonprofit organization that provides educational scholarships to the spouses and children of America’s fallen and disabled service members. The winner will also get flown out to Los Angeles to take a joyride with Malone.
