Worker slashed outside popular Park Slope diner Dizzy’s

A knife-wielding criminal stabbed a beloved Dizzy’s Diner employee outside the popular Park Slope restaurant — and co-workers now need help raising cash to pay for his hospital bills.

Guadalupe Morales — a 41-year-old late-night porter regulars call “Lupe” — was cleaning outside the eatery at the corner of Ninth Street and Eighth Avenue just before 2:10 am on Sept. 1, when a man slashed his neck, back, and chest, cops say.

The perp — described as a 20-year-old wearing a black tank top and jeans — then ran towards Prospect Park, disappearing before police could catch up.

An ambulance rushed Morales to Kings County Hospital, where his condition soon stabilized, said concerned co-workers.

“Lupe is one of the sweetest guys here. There’s always smile on his face and he’s an incredibly hard worker,” said Dizzy’s manager John Hurley.

That’s part of why customers and co-workers are donating money to help with his medical bills and recovery.

Hurley said people can drop cash in a jar at the restaurant and that a more organized fund-raising campaign will likely begin by Friday.

Cops are still hunting the attacker, saying his motive is unclear.

“Nobody knows why it happened,” a 78th Precinct source said on Tuesday.
