Follow-up question to heavy smells in library policy

In reviewing your response to a question on Nov 17, 2020 from an adjunct library science professor, your advice is to create a "smell free zone" in the library for those patrons bothered by another person's odor. Your reply, however, does not address staff who are complaining as well about a patron's body odor. Often, the staff take the complaining patron's side. Often, the odiferous patron is a regular patron who spends hours at the library often on the Internet where PC workstations are relatively close to each other. Yes, I can tell staff it is part of their job to deal with it but often that results in a demoralized angry staff- not something I want to cultivate.
Thank you in advance! This column is very helpful!
