I guess my mistake was to remove my crankset at home to fit it more easily in the car.
I should have bring it with me, and that whole thing most likely wouldn't have happen.
Did you give the old bottom bracket to the mechanic and ask for the same one?
Did you tell the mechanic it was for a triple?
It sounds like the mechanic made the mistake. Learning to do your own wrenching is a good thing. The only thing you may have done wrong was not offering enough information. I think you did the right thing.
