No, it was more funny that anything. We finally paid our bill and our waiter gave us like 20 pesos in single pesos for the change. Which sucks because you can't use single pesos (it's like getting change in all pennies). Also according to our spanish teachers it's an indirect way of saying "fuck you". So we paid the guys tip which came to be like 25 pesos, in the 20 singles he gave us and the rest half pesos.
