Terrible service. They treat you like they owe them everything. On top of that, they charge a mandatory commission. You ask for 100 and they give you 99, you ask for 200 and they give you 198. (Someone will say, "But one peso, two pesos is nothing," but the point is they do this to everyone who goes there, and even if people don't complain, they still feel ripped off.)
