On the subject of "sorry", I loathe the pre-recorded station announcement telling us (yet again) that the 08.45 to London Bridge is delayed by xx minutes and: "I am sorry for the inconvenience this might cause to your journey". No, you're not sorry - you're a pre-recorded announcement. No human being has felt the slightest twinge of remorse or regret about the delay, so shut up and run the service better.
