Punctuality vs Service

Punctuality versus service
,...........
How many times have you miss a bus ,train or plane by a whisker. Whom did you blame or cursed ? Yourself or the service provider? Yes more the services become punctual we have more disgruntled people. Imagine an office goer with his briefcase boards the bus on time but the mother with 2 children can't reach it on time, even if she reaches on time the suburban trains with automatic door closing will close as per the set duration.
So we have a satisfied office goer but also we have a harassed mother with 2 children might be rushing for an appointment with doctor. Lucky that some modern offices have started flexi timing,in some countries there are buses every 5 minutes to tackle such issues.
The time for our daily chores is an approximation and not on the dot time like countdown of a rocket in NASA, it is not that sacrosanct. But the pressure to be punctual remains and which affects health.
I remember once me and my wife were returning in the night at about 10.20 or so after attending a function in Dhakuria,Calcutta. We were returning to our place of stay in Ballygaunj Station Road and local train from Dhakuria was the convenient mode of transport. The last train from Dhakuria station was at 10.30 pm,we reached the station and headed for ticket window,the train had arrived and it stops for 20 secs. By the time we headed to catch the train it blew horn and started. The guard's compartment,the last bogey passed us. The guard looked at us helplessly standing ,he gestured at us showing the direction of the train moving, I nodded "Yes". To our surprise the train stopped for us at a distance and a few compartments were still reachable on the platform. We rushed and boarded the train,while running I mouthed "a thank you" to him.
I am sure with a minute or two delay the train made up it's time leaving a satisfied customer like us.
I am not sure whether with all those automation and stress on punctuality I can have a repeat experience.
