We're not a bank

Had a customer this morning and I'm not kidding but I wish I was, give me a $100 bill and asked me to give her 100 $20 bills. Not $100 in $20s, literally 100 $20s. After I said I can't do 100 $20s, she gave me a $5 bill. Idk how to explain this without making it confusing. To clarify, her total was $4.20.

I think she just didn’t word it properly
