The Yellow Cab you below is a metered taxi service cab with a KC 2227 sticker. It was picking up a passenger at the Manila, Philippines International Airport. It also had another yellow inspection sticker indicating that this particular cab had a meter that had been tested(calibrated) and sealed.
Long ago in the great state of Florida USA, I was ripped off by a taxi cab driver who drove me all over the place leading to a huge fare when he dropped me off at a Jacksonville Hotel.
We have the German inventor Friedrich Wilhelm Gustav Bruhn to thank for the creation of the fraud deterring taximeter which is “visually sealed” after it has been properly calibrated. I don’t know what regulatory entity in the Philippines might periodically inspect the visual seal corroborating that cab owner/operator had NOT tampered with its accuracy duping unsuspecting customers/passengers.
Generally speaking, this island nation, is much more lax on regulating fraud and gouging than in the United States where cable TV, phone, power, gas, water, and other utilities are tightly controlled to protect against unfair over billing. If the tricycle operators sense you are a foreigner with no idea what the fares are, they will rip you off big time. Fares in a typical Barangay(Filipino term for neighborhood) for a trike ride are around 16 pesos which is about 35 cents(dirt cheap in America). However if the trike operator senses you are a “clueless American”, he could go as high as 60 pesos which about $1.33 USD.
