Not being mechanically minded....anybody hear of this?

That mystery clicking noise returned on my new Klein during my 26-mile ride today. Yesterday my LBS said the bottom bracket was a little loose and they tightened it. No noice for the first five miles today, then it was back.

Took the bike back in today and they speculate debris in the crank or a loose screw. He'll take it apart and clean it up. Heck, the bike only has about 400 miles on it!
