If you have been following the curiosity of the London bus slogans...where London buses have been allowed to carry atheist propaganda such as : "There's probably no God ... now stop worrying and enjoy your life."
Then you probably won't be surprised to read (here) that at least one driver has refused to drive a bus that has such a slogan. It's interesting that his company have decided to try and let him drive other buses which don't carry the offensive (to him) ideology.
It raises the question of whether Roman Catholics might not have to drive buses that advertise contraception, or pacifists buses that advertise the armed forces.
It's a bizarre little world.
