Most non-hospital medical facilities are dropping mandatory masking for both staff and patients within the past month or so, especially if they are focused on something like ortho or GI that has nothing to do with Covid or Covid symptoms. The outpatient facility I work at dropped requirement last week.

With urgent cares, you don’t know what people are coming for and a common thing is for serious flu or Covid symptoms. So likely the UC you were at has masking rules for patients but staff rules have been relaxed. They may not even require staff to be masked while interacting with patients anymore and it’s up to personal preference.
