I parked the car on a side street, opened the hatch and pulled out the necessities to fix the flat. Dave was impressed at the speed in which I dropped his old tube and replaced it with a new. I let him know if you do it often enough it becomes as natural as brushing your teeth. He had a high volume/high pressure pump with him so I got him up to about 90 PSI in no time. When I pulled the pump off the stem I forgot to twist the lever so the head of the presta valve ripped off and the tire went flat again in seconds. Shit, I am supposed to be using my mad skills and now I look like a rookie in front of this fellow commuter. I told Dave it was no problem to fix again because I had another tube.
Process over again but this time when I went to install the second new tube I noticed that the valve stem itself was radially cracked half way around. Sorry Dave I had lifted your hopes and now I have crushed them in the same few minutes. He did not seem to care and would not even take a ride saying that he only had a few blocks left anyway. I gave him my card and told him to call me tomorrow which is today and I would deliver 5 tubes to him at the Big Building. He thanked me and mentioned that shortly before I pulled over to help him he had picked up a penny heads up and thought to himself maybe he would find some luck.
