Here is a tip I have found works in some but not all parking ticket dispensers. I get quite frustrated with the machines that have a 2 hour minimum. Especially if you know you will only need 10 minutes of parking. I found this hack by accident one day when I had put a couple of coins in at the same time someone came up and offered me their spot with 1 hour left. I hit cancel on the machine and much to my surprise a ticket still printed out but for 20 minutes of parking time. Next time I was at the same place, I purposefully did the exact same thing and got a ticket for 20 min for $0.50 as opposed to paying the $2.25. I’ve done this now many times and at other locations as well. Do be advised it does not work with all types of dispensers but, give it a try if you only need a small amount of time.
