[Scene] Taking my bike through finch station, on the escalator, bike shouldered walking up the left side, with 1 other person in front

Suddenly I hear this -

Dickhead: WHY BRING A BIKE ON THE ESCALATOR
Dickhead: WHY BRING A BIKE ON THE ESCALATOR (I think he actually said this twice)
Me: (Stops and turns around with my shouldered bike) You have a problem?
Dickhead: No
Me: You have a problem with my bike?
Dickhead: No
Me: Then shut the **** UP

Let's also ignore the fact that I wasn't

a) inconvenincing anyone
b) to not be a dick, I didn't ride through the station like I could have

Guy must have looked at me and thought I was some idiot who would take ****** comments like that sitting down. Seriously what the ****?
