People are rallying around Costco after the warehouse chain faced backlash for requiring shoppers to wear masks.

Starting May 4, Costco rolled out a new policy stating that "all Costco members and guests must wear a face covering that covers their mouth and nose at all times while at Costco," with the exception of children under 2 years old and people with medical conditions that prevent them from wearing face masks.

Angry shoppers took to social media to protest the new policy.

Now, shoppers are speaking out in support of Costco, with thousands of people tweeting with the #SupportCostco hashtag.

Costco's Facebook page has also been flooded with customers showing support for the chain.

"I think it is wonderful that Costco is requiring masks to go into their business,"reads one comment."They are working to keep me, my family and their employees safe during a difficult time. If [you] do not want to be safe, then go somewhere else."

"I totally support your mask policy," reads another."It is small minded individuals who don't understand the reason for it. Covid is not a hoax. It is a serious problem. People are dying for God's sake. Suck it up and protect others."

Costco did not immediately respond to Business Insider's request for comment. In response to a request for comment on the backlash last week, a Costco spokesperson directed Business Insider to a public message on the company's website from CEO Craig Jelinek.

"We know some members may find this inconvenient or objectionable, but under the circumstances we believe the added safety is worth any inconvenience," Jelinek wrote. "This is not simply a matter of personal choice; a face covering protects not just the wearer, but others too."

Some angry shoppers are taking extreme actions against retailers' new safety policies

The Centers for Disease Control and Prevention recommends people wear face coverings in public settings to slow the spread of the coronavirus. Businesses that are open have adopted new policies to encourage social distancing, as well as other safety measures.

Retail workers have been forced to deal with customers who are unhappy or angry with these changes. Three McDonald's employees were shot and a Family Dollar security guard was shot and killed in the last week in incidents where shoppers reacted violently after being told about new safety policies.

Last weekend, police were called to a Costco store in New Rochelle, New York, after a crowd waiting to enter the store became aggressive when the warehouse opened 30 minutes later than expected.

"In 30 plus years of studying retail and crisis situations, we have never seen a situation of customers being so rude to hourly employees," Larry Barton, a professor of crisis management and public safety at the University of Central Florida, wrote in an email to Business Insider's Mary Hanbury.

"It's demoralizing and, as we saw with the shooting of the security guard, a sometimes deadly environment," he added.

Despite a vocal backlash, most Americans support social distancing and do not feel comfortable with nonessential businesses reopening.
