On early busses

Me: “If the bus is scheduled to leave at 12:57 then it ought to leave at 12:57, NOT at 12:55..”

K: “We should have left 2 minutes earlier, then we’d’ve caught it.”

Me: “No, we were there at 12:56, that’s early. The bus should leave when it’s supposed to!”

K: “But you can’t rely on should. Sometimes they leave early. That’s the way it’s always been.”

ARGH.

I give up.

Even 13 year old boys here have been programmed to be über punctual and think it normal.

What’s the point of having timetables if you don’t stick to them?? If everyone knows they leave earlier than planned, why not just change the plan?

I think busses which leave early are worse than busses that run late.
