“We have gotten 25,000 complaints, to the state, of businesses that are in violation of the reopening plan,” said Cuomo. “We have never received more complaints in a shorter period of time.”

He added the complaints have come mostly from Manhattan and The Hamptons.

Cuomo said he would “reverse” course in regions where the state’s reopening plan is not being followed.

The governor said inspectors from the state Liquor Authority are out, along with a task force of state investigators.

“If you are an individual, you cannot violate the open container law,” said Cuomo. “You can’t stand on the sidewalk, drinking a beer.”

“I understand it’s not popular. Nobody wants to go to a sidewalk with people drinking and say, ‘You people can’t drink on the sidewalk,'” said Cuomo. “You know what’s more unpopular? If that region closes because that local government did not do their job.”
