Is a chemist a pharmacy or a pharmacist?
I'm trying to figure out if you need the personal a if it is just a particular person and not if it is the name of a person's job. So here, if chemist is a pharmacist, I don't use a personal a because it isn't a specific person.
OR.
If the personal a is for any person and here chemist is a pharmacy, not a pharmacist.
Thanks!
