"There is an app for a local burger chain where it allows you to “roll the dice” to get a code for a free double-patty burger upgrade. It was designed so you could only try it once per day and it even shows the date of the roll on the code so the cashier could verify it.
However, I found out that you can just change the date on your phone and try again immediately. If you got nothing, change it again and just keep going until you get the code. Then, when you got the code, you change the date back to the current date and the app updates the code so it looks like you rolled it today.
I got free burger upgrades for years until they finally got rid of the feature altogether. I don’t know if anyone ever figured out this exploit, or they removed it for other reasons."

Most of the time, the operator knew the number was a pay phone. After ~5 tries, we would get an operator who didn’t know or check that it was a pay phone.
