I didn't think the bike chain jumped before getting the work done. Thought somehow the front chain rings got moved to the right during BB bearing replacement, thus enhancing the crossing of the chain. Can't verify this though.

So it's normal for the chain to move to a smaller sprocket during back pedaling in big to big position? My road bike doesn't do that. Just try to determine "normal" behavior for a mtn bike before returning to the shop.
