Bruce Willis was reportedly asked to leave a pharmacy earlier this week after refusing to wear a mask.
According to a report from Page Six, the incident occurred in a Rite Aid branch in Los Angeles.
People inside the shop became upset and annoyed that Willis wasn't wearing a mask.
The actor was photographed at the store without a mask on, and had a bandanna tied around his neck.
Page Six's source says Willis left without making a purchase.

Masks are required in all indoor spaces under Californian law.
LA is one of the worst-hit cities in the USA in the pandemic, with over 930,000 COVID cases.
The actor has since released a comment about what happened.
He told People: "It was an error in judgment."
He added: "Be safe out there everyone and let’s continue to mask up."
Bruce Willis has spent much of the pandemic quarantining with ex-wife Demi Moore (who recently starred in "pandemic thriller" 'Songbird') and their adult children, Scout, Rumer and Tallulah, at the family’s home in Idaho.
