A couple likely wasn’t “lovin’ it” Wednesday afternoon after being robbed of their McChicken sandwich and coffee by a knife-wielding bandit outside a San Francisco McDonald’s, police said.

The Hamburglar struck at 3:30 p.m. in front of the golden arches on Market and Second streets, pulling a blade on a 47-year-old man and 58-year-old woman, officials said.

Police later apprehended the yet-to-be-identified McChicken mugger.
