As for the stem/bars moving too easily, the problem is that with the compression plug tightly secured, the stem does
not move especially while on the trainer where I do no turning. Isn't it possible that they just screwed the plug in and figured that that was good enough or they made a mistake?
As for the C&V gods, I prostrate myself seeking forgiveness. At the time, I wanted to lighten up the bike so swapped out a beautiful chrome fork for the carbon

. If only!!!!
I guess it's possible, but unlikely. The shim is inexpensive:

Just put the stem and shim on with the clamping bolts loose, tighten down the compression plug until there is no play on the headset and it turns without too much drag, then tighten the clamping bolts on the stem. If all else fails, hopefully you kept the original fork. If the LBS took it, then yes they screwed up.
