Regarding the message “There’s probably no God".” on 800 London Buses (in response to a religious one telling people to look up a biblical verse telling them they are going to hell), there was a woman tourist from LA is quoted: “I think it’s dreadful,” … ”Everyone is entitled to their opinion, but I don’t like it in my face.”
I really enjoy the irony, and the bonus irony that the “probably” was added to meet advertising guidelines.
