What can you say about the "pay toilets" in the Philippines where one needs to pay 2 to 10 pesos per excretion?

When you happen to visit the Philippines, make sure to always have loose coins or smaller denominations in your pocket, otherwise you have to hold your urine or bowel against your will! You have to know that "pay toilets" is everywhere in the Philippines, including some if not all parks, terminals, restaurants, etc.
