Continuing the series, when I moved to Germany I was surprised at how passionate Germans could be about their bubbles.
This sight of clear glass inspection windows will raise no eyebrows at any petrol station in Germany:
You’like likely to find a big sign with the words Blasenfrei zapfen – which, loosely translated, means: relax, don’t worry. We’ll show you the gas flowing through the line to convince you it contains no bubbles and we are only charging you for gas, not air.
What people have told me: Americans also were concerned about bubbles in their gasoline – and gasoline dispensers in the U.S. had similar means to see the flow of gas. In the U.S., however, this practice seems to have died out in the 1950’s.
