How about combo odors ?
Many years ago I unlocked the front door and stepped into my business. The insurance company next door had been chemically cleaning their ceiling tiles. The beauty shop next door had perm and setting solutions. I was recovering my pool tables and the glues used had vomit inducers to prevent sniffing, ignoring people that have to work with the glues.
I almost puked when I stepped in. Had to open all the doors and run fans to air it out.
