Credit cards can be complicated in the Philippines
You get used to credit cards being the quick and easy way to pay in the States. But it isn't so quick or easy in the Philippines. Every transaction seems to involve long waits and multiple receipts. On top of that they always seem to need a specific sort of credit card machine depending on what kind of card you have, I guess.
A recent store I went to had EIGHT different credit card machines. I took a photo just so people would believe me.
