Scaring off the passengers
So, I was riding on one of the new local trains this afternoon. I noticed two unique aspects of these new trains. First, the funny and often confusing announcements from the train personnel over the intercom system are gone. Now there is a calm slow-speaking male voice that sounds somewhat like a smart robot announcing all the information. (Or, maybe it is just someone who no longer speaks like a normal human being.) Secondly, if you try to open the bathroom door when someone else is in the bathroom, there is a loud voice coming over the intercom for all to hear (!), stating the toilet is occupied and please come back when it is free. You have never seen someone disappear so quickly. It was hilarious to see how people raised their faces from their cell phones to see who dared touch the bathroom door. This might be a good way of scaring off passengers considering using their toilet facilities.
