Some examples of situations that call for a payday loan are:
- Pet needs to see the vet
 
- Power bill is overdue
 
- Car is broken down and you can't get to work
 
- You need to go to a wedding or funeral
 
- Buying groceries
 
It's easy to get in over your head if you borrow too much.  The State of Michigan has limited loans to $600 which is one means of mitigating that sort of risk, but it does little when someone who earns $600/paycheck gets a loan for $600.  They are basically guaranteeing that they will be in a debt spiral from that point on.
This is why we have voluntarily limited our maximum loan to be 50% of a person's net income.  This leaves at least 35% of the paycheck to be used for getting by to the next paycheck without needing an additional loan.
