Now that I am again a frequent user of public transport, the automated announcements have become part of the white noise in my head:

I got a good laugh from this little article in New York Magazine. Apparently MTA subway riders got really ticked off every time the train would become delayed and the automated announcements would say, please be patient. You can read this funny article here.
