This argument was a real purse-saver!

A thief wanted no part of this would-be victim amid a heated squabble with a pal, surveillance video shows.

The video shows two women arguing as they’re walking through Bedford-Stuyvesant at around 4:40 p.m. on Oct. 4.

The thief then grabs the 38-year-old victim’s purse and attempts to rip it away — even as the duo continues bickering — leading the suspect to ultimately give up.

The suspect is described as a 20-year-old black woman who stands 5-foot-10 and weighs about 180 pounds. She was wearing a black shirt and a Chicago Bulls hat.

Police are calling the other woman a person of interest.
