NEW YORK (AP) — Burger King is delivering its own hot take on a regulatory showdown that has enflamed the U.S., using a flame-grilled Whopper. Burger King's new ad has become a sensation, with more than a million views on YouTube and it's lighting up Twitter . In the ad customers, whom the restaurant says are real, are told they will be charged different prices for a Whopper, based on speed, or MBPS (making burgers per second).
