I may have been there a bit before you but cabs were cheap. They had the big yellow jobs.I shudder to think what I payed for towing when I was a student - and I couldn't afford it.
Most times, I'd let the garage or lot keep my car until I could afford to pay the fee. I'd check to see how long i had before they started piling on penalty charges and find a way to pay it off before then. Several times I missed the deadline and barely got the car out before they took possession and sold it.
If there was anything like Uber back then, I'd not have felt the need to have a car.
We also had pledges. Problem was...they were usually drunk. I was nice and always bought their taco bell or other drive through.
