Rail employees try not to travel in their uniforms. If you do, you run the risk of having someone have a loud pointed conversation on the next seat about how crap Metro is (apparently you are supposed be so cut, you go home and sort this out) or how Myki (the ticketing system) is the worst thing that ever happened (Seriously if this is the worst thing that ever happened to you, I wish I had your life.)
However the other day, I didn’t have time to change. As I pottered down the aisle looking for a seat, a young man did a double take, seized his laptop and fled out from the carriage. Lol! I suspected, and the woman opposite thought so too, that he feared I was a ticket inspector bringing fines and recriminations. Even though I am the greeniest, leftiest, bleeding heart liberalist person you are ever likely to meet, I enjoyed a dazzling moment of evil villain glee at having a young man flee before me. Bwahahaha! Everyone has an inner fascist somewhere.
