Yes you are obnoxious. I slow down and ask everyone if "everything alright" if they are on the side of the road. I carry a tube, patch kit and two CO2 + mini pump. I have patched tubes for folks, shown them how to change a tire w/o turning their bike upside down and destroying the beautiful ST-7700 cover plates, etc., but if they ask for a tube I tell them good luck because I might need it.
