Just because it's Christmas doesn't mean you may dictate how much you charge your passengers. Gasoline is at its all time low for the last 10 years for sanity's sake! Isn't that enough compensation for the holidays? An additional 30Php is not right, and a 150Php fare for a 90Php journey is worse. Besides, you'll be getting a lot of passengers throughout the day wherever you go due to the Christmas rush.
Also, I must remind you that not only is this illegal, but choosing passengers is unlawful as well. Too bad our law enforcers don't do anything about it.
tl;dr: Fuck you, choosy drivers.
