Have you heard of underground rage? Well you heard it here for the first time!

Early morning I was walking down the escalator steps and on the last two steps I slowed down and stopped to carefully step off the escalator. Then I suddenly got ambushed from behind by a man so he hanged on my back. He said. You cannot stop in the escalator! With a high and irritated voice. I replied camly. Sure I can stop walking. When we both were walking to the train he then suddenly demonstratively stopped I front of me so I almost walked into his back. He said something about me and my mobilephone. I just said that one should be careful when walking off an escalator. He disappears.
So I was the victim of escalator/underground rage. So there now you have heard of underground rage.
