That's OK. I once saw somebody make three stops on one short string of errands. Stop one, go in for a minute, come out drive the car 1/2 block to the 2nd stop, then make a U-turn and drive back to the middle of the block for the 3rd errand. The total distance covered must have been less than 50 yards + crossing the street.

People are lazy.

OTOH, while inconvenient for you, there's no rule about stopping on shoulders, and you should be ready and willing to ride around obstacles. If there were a huge pothole in your path and you had to maneuver around it you wouldn't have posted about it. Lazy or not, humans deserve more consideration that potholes, so while you may not like the behavior, try to make room in your life to take it in stride.
