You might be adjunct if: a collegue mistakes you for a student using the copier without permission...
....you have to have all of your copies made at Staples and don't get reimbursed for them.
....you hold our "office" hours in a corner of the library.
....you have to make up your own "departmental letterhead" for writing LoRs b/c the dept doesn't give you any (or a file with it watermarked in).
....on long days on campus you eat your brown-bag lunch in the lobby or an unused classroom of your building b/c there's no lounge you can use.
