I once had an experience with one of those "Payday Loan" places.
Borrowed $130 dollars to get my car repaired back when I was down south. They told me the interest rate was 80% on top of the amount due in a week or interest would start to accrue and if I didn't or couldn't pay, my car would be forfeit.
That shyt IMMEDIATELY reminded me of the loan sharks back in NY...so I knew what fukkery I was dealing with.

I got the $130 and agreement papers, they got my car title.
A week later, I came back on the agreed upon date and time with the full cash payment in hand.
They looked at me like they couldn't believe it...like they halfway didn't want to accept the payment.
I coughed loudly at the dude and said "I'm here to settle my account" to get his attention.
He must have asked me 8 times if I wanted to take out another loan or extend this one before he gave me my damn car title and paperwork back and closed out the fukkin loan.
Never went back to one of those.
Everything about them reminded me of the loan sharks back in NY.
The only thing they didn't do was raise the amount when you show up with what you owe, so you never get out from under their thumb.
