This afternoon, I was out with a friend to go and see a film at the cinema. After we finished the movie, we walked back to her bus stop, which departs from the Broadmarsh bus station. While the Broadmarsh closes in the evening, there is a "tunnel" through it that is open as a way of allowing access to the station.
My friend and I made use of this tunnel and I should note that she is not a fast walker whereas I am and so I walk at her speed when with her. When we were about halfway through the tunnel this evening, I heard a voice from behind me ask, "Could you walk any slower?".
The words came from impatient person, who could quite easily have either gone around my friend and me (there was plenty of room to do so) or have politely asked us to come through. But no, apparently this required too much brainpower for them; immediately resorting to sarcasm was apparently their only option.
While I ended up letting them through (more like because I moved out of the way instinctively, not because I wanted to let them pass), it wasn't without a comeback of my own. My response was, "Why, yes I can, actually!".
