Approximate value: US$0.005.
So this morning I went to the grocery store to buy a bottle of juice worth 24.25 pesos. I gave 30 pesos to the cashier. She asked me if I had a 25 centavo coin, and I said no. Then she gave me a full 6 pesos of change anyway.
What's the point of asking for the 25 centavos if it doesn't even matter?
P.S. The macro on this camera is incredible.
