There seem to be rather unpleasant aromas wafting from the other patrons. Is there anything that can be done beside having to move to escape the odors?
Sadly, issues involving the sense of smell fall mostly outside the librarian’s purview. If the offensive smell came from a piece of equipment, moldy book or a library staff member, then something could be done. Likewise, if the complaint was noise-related (that is, involving the sense of hearing) then we are able to step in.
With this situation, it seems you will have to go with the approach you suggested – relocating to another part of the library.
