I have had to make an allen wrench out of a piece of thick wire I found on the side of the road to tighten a rear derailer's pulley bolts. I just kept rubbing it on the concrete to make edges. Freak need but I always have my pulley size with me now.

Ok I am done with my serious posts. This story gives new meaning to the bike term "head tube" "Bottom Bracket" "Crank" and the the technique of "Reaming a headtube."

Arborman, I agree that a person should not have to open a door in a private setting and I also have not a care what people do to things or each other as long as people (or animals) are not being hurt. In this case the people knocking repeatedly were housekeepers who were presumably just trying to do there job. Being a housekeeper seems like it would be hard enough without people exposing themselves to you while you attempt to work.

I have to believe in this situation the real offense was not identifying himself when the door was knocked on and apparently not immediately stopping as the staff entered the room.
