Full tank, empty pocket

I think I'll have to start walking or biking to work sooner or later. When I had the gas tank of my car filled earlier before my trip to Manila I was shocked to see that unleaded gasoline now costs more than Php50 per liter. Consequently I had to pay more than Php1555 for just half a tankful of gas! (The indicator of my car's fuel gauge was on the first tick below the halfway mark.)
