I used to manage a Kinko's in college. We handled graphics, printing and copying for several businesses in downtown ATL. Local hip-hop street team cats would come in to get prices on flyers, cards, mixtape covers...etc. and once I hit them with the legit design and printing prices they freaked out.

...then I hit them with my personal after hours price.

Sometimes I ended up doing jobs in exchange for tickets, weed, gear, CDs, sneakers...etc.
