When I was a kid in Laos (maybe 6 yrs old) I was sick and had to go to the hospital in the big city. My dad must have taken me there in a taxi, and so we had to take a taxi home. I recall very well (on the ride home) even at that age a milk jug like dispenser mounted on the dash in the taxi. I must have gotten dizzy from the fumes because I recall my dad tell the driver to roll down window or asking to roll down the window. I remember there were gradulated marks in the dispenser. That was the taxi meter!
Back in the 70's it was "anything go." it's probably not changed much there.
OMG... Really? Talk about making do.
