I'm a bus driver. The job not only involves driving but also allowing (or not) the carriage of passengers if they should qualify for a concession.
For instance elderly people can't claim their concession during certain times of the day. Students have to show a card to qualify for a student fare. Purchase a ticket & you get a free hour's use of it. But I don't care.
The elderly get their concession fare whatever the time of the day. 'Students' just need to ask for a student fare & I give it out, no ID required. If someone brandishes a ticket and it's expired after an hour I don't care. I don't care if it's a week out.
I'm not a policeman. And that's the difference between a Conservative & a Liberal. We don't suck up to the Trump's of the world. The real liberal agenda continues, drip by subversive drip...
