A coalition of more than 500 bars introduced strict pandemic restrictions to counter soaring Delta variant cases in Northern California.

The San Francisco Bar Owner Alliance confirmed its members require customers to present proof of vaccination, or a 72-hour negative test, when entering bars in the Fog City. Customers without valid evidence may be permitted to sit outside.

The alliance claims these tighter measures are meant to ensure the safety of workers and patrons.

“This decision is based solely on our need to protect our workers, customers, and their families,” a representative said in a statement obtained by ABC7News.

The organization hopes these restrictions will compel more Californians to take the jab, because it supposedly returns more normality to society.

“We hope it might also influence some who have not yet received vaccinations to do so as soon as they are able,” the representative said according to the broadcaster. “The only way our society (and our businesses) can ever return to true normalcy is through higher rates of vaccinations among our residents, not just in San Francisco but across the United States of America.”

Each establishment will be individually responsible for enforcing the policy, which took effect on July 27.

Vaccination has not slowed the rising number of bar workers who contracted the Chinese Communist Party (CCP) Virus. However, the alliance suggested the measure would at least bring some peace of mind to the local industry.

“We believe we are obligated to protect our workers and their families, and to offer [a] safe space for customers to relax and socialize,” the representative said according to NBC News.

The alliance revealed it surveyed its members and found 85 percent of them support the measure, according to NBC Bay Area.

Founder Ben Beilman revealed most establishments have welcomed the decision.

“We are getting overwhelming responses from customers, regulars, and the public saying ‘I am going to feel safer in your establishment so I would be more opt to go there,'” he said in a video shared on YouTube.

The California state Legislature previously declared public employees and healthcare staff have to show proof of vaccination, or undergo weekly testing for the virus, to help curb the CCP Virus’s rapid spread. 

The state Department of Public Health revealed 83 percent of the city’s eligible population already had at least one shot, while 76 percent were fully vaccinated at the time of publication.

Mayor London Breed (D) recently revealed six out of 1,800 hospitalized patients were breakthrough cases.

San Francisco experienced a seven-day average of 185 new CCP Virus cases, representing a dramatic uptick from 12 reported during the seven-day period at the beginning of July.
