I was once a replacement bus for the first half of a journey, planned to connect into a regular train for the rest of the journey. The bus was a few minutes late, so the connection became tight. There was a line of people walking from the bus to the train, those at the front had got on the train, those at the back hadn't yet reached it, but the staff just despatched the train bang on time without any warning or attempt to hurry people up (but were very good at shouting "step back from the train" after they'd started the despatch). I would have argued that if nobody was going to make the connection, it would have been fine to despatch on time, but letting some people make it and some not was just bloody-minded.
Some people tried to discuss this (amicably, not shouting/yelling) with the staff involved afterwards, and were met with some frankly awful responses that included "do you know how much our company gets fined if we despatch late?", "feel free to complain about me on twitter if you want, I'm doing my job properly so nothing will happen" (both of which might be true but aren't exactly going to win awards for customer service) and "I didn't know the bus had just arrived" (even though you could see the car park from the platform).
And we wonder why people run towards closing doors, hold the doors for others, etc...
