Why are my cables crossed??

[ny biker]

I just turned my bike upside down to clean it, for the first time since I paid the usually-reliable LBS to take it apart, clean it, reassemble it and tune it up. And I find this -- the cables are crossed.



I have never seen this before. WTF??

I had to go back to the LBS twice after the clean and tune for derailleur adjustments due to massive shifting problems. It never occurred to me to inspect the cables.

I really do not have time to go back there again and have this fixed.
