Touching on and touching off without thinking

The small plastic card readers positioned near tram and train doors have become so familiar that most locals barely register the motion of tapping on anymore. It happens automatically, a card pulled from a pocket or bag in the same beat as stepping aboard, no conscious thought required.
Forgetting to tap off, however, remains a distinctly local anxiety. A missed tap can quietly cost more than intended, so regular commuters develop a kind of muscle memory around the whole sequence, checking almost reflexively as they step off at their stop. Locals who have missed a tap even once tend to remember the lesson clearly enough not to repeat it casually.
Visitors sometimes find the system's informality surprising, since enforcement can feel inconsistent compared to more rigid systems elsewhere. For locals, though, the trust built into the process is simply how things work, a quiet assumption that most people will do the right thing. Enforcement may look relaxed, but the underlying trust between rider and system rarely gets seriously tested in practice.
