Laptop for home use because I teach online, ipad as part of winning a grant - meant some grant reporting responsibility in addition to the original application.
Free parking, as if that were a perk in the rural South. Except mine's no longer free since we now pay $65 a semester for a student pass for my husband in spite of carpooling. (He doesn't even have the pass, just the fee). No getting out of this; I have a student who is blind and who has to pay this fee.
Every now and again there's food, and sometimes it's edible (our upcoming faculty retreat lunch is not an example of edible - very popular, very greasy fast food hamburgers and fries, no options for vegetarians, allergies, etc at all).
Library and database access, though, is a big deal. We have a small library on my campus, but I have access to all of the state univrsity system plus most of the privates, plus university libraries in the neighboring states as a courtesy. I can interlibrary loan from the state flagship, which is a major research library. There's not really any scholarship produced in English that I can't get my hands on in a week or two. I'll have similar access when I retire, assuming academic library access still matters in a few years.
Books from publishers, oh, my god the books. They won't stop sending them, unrequested and unwanted. I've taken to handing things back to textbook reps when they come and interrupt my work.
I think I get some athletic event access, but I'm not sure and don't much care. I'll go if I ever have students to whom it seems important to see me there, but that's more work obligation, not a freebie. There are concerts and lectures that matter to me, though. There are also plays, but those are not free. I go anyway, and the cost is low; they just don't count as freebies.
