A homeless man attacked a pair of elderly diners outside a coffee shop in Lower Manhattan, cops said Thursday.

Police said the 47-year-old vagrant approached the couple outside Think Coffee on Bleecker Street in Noho, telling them they “were being disrespectful for not giving him money.”

The unhinged man then shoved the 61-year-old to the ground and hit the 75-year-old woman in the side before taking off, cops said.

Each suffered minor injuries and refused medical attention.
