Things get lost. If you list the address for one employer, list it for all. Give the address in the same font, format, etc. Don't think that because you're a pharmacist people won't care about details like grammar. Don't try and throw a resume together at the last minute.
Communicating concisely takes a few tries, and proofreading errors are sometimes hard to find.
Write the resume and let it rest a bit before you look at it again. Again, it's just a matter of neatness, attention to detail. Typewritten or dot matrix printed resumes are often hard to read. Editing is also more difficult when you use a conventional typewriter.
