I think at some stations that actually is the correct stat, that only 50% pay. I can use 34th as an example, I do go to Drexel but always pay but definitely when going out at night, I don't think anyone else bothers to pay.

There is no SEPTA attendant and no real encouragement to pay, just out of good faith.

Also yeah everyday I leave city hall, someone comes in behind me on the handicap one haha.
