For some reason I always hold my breath until they are out of range (like I'm 4 meters away from them). I don't know if that works lol. But of course politely reminding them (while not facing them and increasing your distance) that they are endangering others is the most effective way.
Other than politely reminding them, what would you do?

I just move away from them when I can, which is most of the time, and will bring up physical distancing if I feel comfortable.
