Police getting on buses
It's common to see uniformed police getting on buses in Greater Manchester and I've noticed they are able to get on for free understandably so.

But is this down to bus company/tfgm policy or just goodwill from the driver? I hope it's both to be honest.

Same goes for drivers of rival companies, is that like a comradery thing aka good will or company/tfgm policy?
