Dang! Some older lady yelled at me if I was warning people as I passed them on my bike today on the Ada Hayden path! Must of thought I was riding too fast as I passed her at least 6 times. For the record not only did I warn people "on your left/right/middle" I aslo slowed down and said thank you as I passed. Some people aren't happy unless they complain. Geez!! It is kinda hard to warn those that have their headphones/airpods in though. I about got taken out by a German Shepard on a 15" leash.
