Galluswarte S-Bahn station, at half past seven in the evening, on a train towards the city centre.
Most seats are occupied, many passengers are standing at the entrances or in the aisles.
Just before the doors close, two inspectors get on.
"The tickets, please," they say;
a demand that triggers hectic activity in one or the other.
A woman rummages in her handbag, a man, looking for his 9-euro ticket, drops his wallet in shock, other passengers quickly put on their masks hanging on their arms or necks.
Only two men drinking cans of beer, regular visitors to a fitness studio to judge by the size of their upper arms, face the impending inspection unmoved and unprotected.
"Have a good trip", wishes the man from the inspection brigade after a quick look at the tickets of the two grinning provocative passengers.
After all: no fare dodgers.
The inspector, whose colleague is now on duty at the other end of the car, ignores the fact that two passengers – because they were not wearing a mask – violated the conditions of carriage of the Rhein-Main-Verkehrsverbund (RMV).
No verbal warning, no fine.
That would have been 50 euros per head, but probably also at least a verbal argument with the two ignoramuses.
Then it's better to pretend you didn't see or know anything.
"My name is Hase," the inspector says to himself, and when he has long since fled, a woman over 50 speaks to the mask muffle.
"But you know that you have to wear a mask here?"
"Am I Zoro or what?"
Of course not, and with that the story comes to an inglorious end.
The two men drive on - without mouth and nose covers - the observers of the scene without understanding for the ignorance of the three main actors.
What use are rules if compliance with them is checked little or not at all?
The number of people who absolutely don't want to be Zorro on the bus and train is increasing day by day.
Maybe the RMV should use the Terminator in return.
