Winds at LVK normally favor landing to the west, but this day they were landing to the east. Runway 7L is 6000?, and has a parallel taxiway to its left (north). Runway 7R is much shorter, and its threshold is about 2000? further east than is 7L?s threshold. Overheard on tower frequency:
Tower: Cessna 123, cleared touch and go, runway 7 right.
C123: 7 right, cleared touch and go.
Pause
Tower: Cessna 123, you just did a touch and go on 7 left, you were instructed 7 right.
C123: No we didn?t! We were cleared 7 right!!
Tower: C123, turn left, left base. (Pause). Now turn left, left downwind. (Pause) C123, look out your window. What?s painted on the runway?
C123: It says seven...uh,...uh,..left. How can that be??
Tower: Cleared to land, full stop. Taxi over to the tower.
