Strange sightings on Adelaide Rd

I was headed to Wellington Hospital this afternoon for a routine physio appt and sited two old men fighting on the footpath. One guy was on a bike, the other had a cane. It looked like the older gentleman with the cane was having a go at the other for riding on the footpath.

I couldn't help giggling in my car but I also pulled over and tooted at them to stop because neither looked particularly stable on their feet. Police pulled up on the opposite side of the road also.

Is this a regular occurrence in Mt Cook/Newtown? Honestly they looked like they were late 70s, early 80s.
