Some WU agents will pay you with what they have in the cash drawer.

But, normally you will get a mixture. Remember that almost all of the WU agents also work with Pago Facil and they receive piles of different denomination notes in payments of bills for gas, phone, electricity etc.
It all depends on luck.
