It seems like people get irrationally anxious and angry having to wait behind people moving slower in general. On paths that cyclists share with pedestrians, cyclists are usually even more angry and aggressive with pedestrians than drivers are with cyclists (pedestrians are expected to move out of the way and often get yelled at if they don't). There seems to be this almost atavistic response people have to something in front of them impeding there movement.
