How it works
A very short loan can cost a lot for the days it lasts. A payday loan means: borrow now, and pay it back on payday.
Omar borrowed ten pretend coins with a fee of three coins, so thirteen coins were due on payday.
When Omar was short, he paid the fee and the loan rolled over: two more weeks, a new fee, and the ten still owed.
A cash advance is a card that gives out cash, with a fee taken at once.
