I mean purely as reasonable accommodation is defined by the ADA. Sorry, it looks like my 'as I'm suspecting you know' landed differently than I intended. I meant that you seem to be aware of ADA requirements.

For example, requiring a workplace to provide an employee who requires it an N95 mask very clearly falls under the 'reasonable accommodation' category.

However, requiring all employees or patrons to wear N95 masks does not track with other examples of reasonable accommodations.
