The slightest nudge on a British train often results in a seething glare.
When you next encounter an instance of British reserved judgement think about these commuters in Venezuela who have to run, leap over chairs and swing on poles to get a seat.

When the doors open, the commuters run into the carriage with no regard for other people, including women and children.
Next time it might not seem so bad having to wait a few minutes because the train is too busy.
